Overview

Salt & Steel's visual identity is not a mood board assembled from genre conventions. It is a specific, deliberate artistic stance rooted in the fantastical illustration tradition exemplified by Josh Kirby — an artist who understood that danger and wonder are not opposites but collaborators, that the most monstrous things can be beautiful, and that a world painted in full color hits harder emotionally than one drained of it.

This document defines the complete visual language of Salt & Steel: how it looks, how it is lit, what its colors mean, how its characters and creatures are designed, and how each region of the world expresses a distinct visual identity. Every art decision made on the project should be checkable against this document. If a piece of concept art, a UI element, a lighting setup, or a texture pass cannot be justified by what is written here, it is wrong by default — not because rules exist for their own sake, but because a consistent visual identity is one of the rarest and most valuable things a game can have, and it is destroyed by drift.

The Josh Kirby Principle

Josh Kirby (1928–2001) painted the covers of Terry Pratchett's Discworld novels, and in doing so created a visual language for fantastical fiction that has never been surpassed in its specific achievement: the ability to render an entire world in a single image in a way that is immediately, unmistakably alive.

Kirby's work is characterized by:

Exaggerated, purposeful proportion. His characters are not drawn to anatomical standard. Noses are larger, hands are more expressive, eyes communicate far more than eyes of correct size could. The exaggeration is not caricature — it is emphasis. Every proportional choice tells you something true about the character that anatomical accuracy would dilute.

Color at full saturation. Kirby did not paint in washed-out tones or muted palettes. His blues were genuinely blue. His reds were blood-red and fire-orange simultaneously. His greens were the green you remember from the most vividly colored book cover of your childhood. The world he painted was saturated because it was experienced fully — no emotional distance created by desaturation.

Texture that tells history. Every surface Kirby rendered had layers — age, use, weathering, repair. A wizard's hat was not merely pointy; it was worn at specific angles, faded in specific places, patched with materials that told you the wizard had been somewhere difficult. The world accumulated detail rather than losing it.

Grotesque beauty. Kirby's monsters are monstrous and gorgeous simultaneously. The grotesque does not cancel the beautiful; they amplify each other. A creature designed by Kirby is something you want to look at even while fearing it. This is the quality to pursue in every creature and environment in Salt & Steel.

Energy and movement. Even still images by Kirby feel like they were frozen mid-motion. Characters lean into what they are doing. The world is in the middle of happening, not posed for observation.

These principles — not the specific Discworld iconography, but the approach — are the foundational visual grammar of Salt & Steel.

Fantastical Realism: The Precise Tone

Salt & Steel is not photorealistic. Photorealism flattens the emotional register of a world by making it look like the real world, which the player's eye processes as familiar and therefore unremarkable.

Salt & Steel is not cartoon. Cartoonism reduces emotional weight by signaling through visual code that consequences are softened, that the world is not serious.

Salt & Steel is fantastical realism: the world operates by physical laws recognizable to the player (things fall, fire burns, water is wet, metal catches light) but everything is heightened. Colors are richer than they are in photographs. Weather is more dramatic than it is in life. Characters have more presence than real humans do. The sea is more beautiful and more threatening than any sea you have actually seen. The world is the world, amplified.

The reference comparison that clarifies this: compare the visual registers of PoE and Salt & Steel.

PoE's visual contract with the player: This world is broken, corrupt, and dangerous. Color and beauty have been drained from it by apocalypse. Your presence here is precarious.

Salt & Steel's visual contract with the player: This world is magnificent and dangerous. It will kill you with color in its eyes. Its beauty is real and its danger is real and they are inseparable.

Both contracts involve danger. Both involve weight. But PoE achieves this through darkness and desaturation; Salt & Steel achieves it through vibrancy and contrast. The emotional impact of a golden sky behind a storm on the horizon is not less than the emotional impact of a grey wasteland — it is different, and in the context of a game about the glory and cost of being a captain, it is more appropriate.

The Master Color Palette

Color in Salt & Steel is a language with grammar. Every color listed below carries meaning that must be applied consistently across all visual systems — environments, characters, UI, VFX, lighting, creature design. Drift in color language is the first symptom of a game losing its visual identity.

Environmental Foundation Colors

Deep Ocean Blue — #1A3A5C to #0D2240
The blue of open deep water; the blue of the space between horizon and sky; the color of depth and distance. Used in large environmental masses: the sea surface, the night sky, the shadow sides of mountains and cliffs. This is the world's ground color — the baseline from which everything else departs.

Teal Shallows — #2A8B7A to #40B39A
The color of water over light sand, coral reef, and shallow tropical waters. Warmer than the deep ocean blue; communicates safety (shallow water) and biological richness (reef ecosystems). Appears in coastal environments and underwater zones where light penetrates.

Burnished Gold — #C8922A to #E8B840
The color of sunlight at golden hour, aged wood that has been oiled and loved, brass ship fittings, lantern glow on weathered surfaces. This is the game's warmth color — it appears wherever safety, home, and human care are present. It is also the color of treasure, but treasure is warm gold, not flat yellow. The difference is amber.

Weathered Wood Brown — #5C3D22 to #7A5535
The base color of ship hulls, dock planking, tavern floors, furniture, and any wooden structure that has been at sea. Never clean; always carries the history of salt and spray. The texture of this color matters as much as the hue.

Sail White — #E8E0D0 to #F5F0E8
Not true white. Sail canvas is cream-white, tinted slightly warm from tar and salt. Used for sails, linen clothing, cloud underbellies, foam on wave crests. The slight warmth prevents visual coldness.

Storm Grey-Purple — #4A4060 to #7A6A80
The color of serious weather. Bruised purple-grey, the specific hue of storm clouds at their heaviest. Never neutral grey — always has the purple undertone that communicates supernatural menace as well as meteorological threat.

Danger and Corruption Colors

Blood Crimson — #8C1515 to #C42020
Combat, wounds, danger, violence. Used sparingly precisely because it must retain impact when it appears. A slash of crimson on a ship's flag or a creature's markings reads immediately as dangerous.

Cursed Green — #2A7A1A to #3DAD25
The specific sickly green of supernatural corruption. Not the healthy green of jungle or reef — this green has an internal luminescence that is wrong. It appears on cursed artifacts, corrupted creatures, areas touched by sea-witch magic gone bad.

Deep Abyssal Purple — #2A1040 to #3D1860
The darkness of true deep ocean, the void between stars, the color of the most dangerous and unknown supernatural forces. Appears in the deepest underwater zones and on the most powerful cursed items.

Wonder and Treasure Colors

Warm Amber Gold — #D4902A to #F0B030
Treasure is this color, not flat yellow. Think sunlight through a glass of aged whiskey, amber resin, old honey. This specific warmth is what distinguishes genuine treasure from painted wood.

Gem Prismatic — contextual
Gemstones in Salt & Steel are fully saturated: rubies are blood-deep red, sapphires are ocean-depth blue, emeralds are tropical-reef green. Each gem color should be the most vivid version of itself, not toned down for plausibility.

Bioluminescent Blue-Green — #20E8D0 to #40F8E8
Electric, cold, impossibly beautiful. The color of bioluminescent plankton, deep-sea creatures, certain enchantments, and the phosphorescent wake of a ship sailing through night waters. This color should feel like it produces its own light, because it does.

Light Source Colors

Fire Amber — #E87020 to #F0A030
Lanterns, torches, hearths, cannon flash. Warm orange-amber light that humanizes any space it touches. This is the color of survival and civilization against the cold dark of the sea.

Moon Silver-Blue — #B0C8E0 to #D0E8F8
Moonlight at sea is colder than sunlight but not harsh — it has a blue-silver quality that makes the water look like moving glass. Night scenes should have this as the ambient light when the moon is out.

Golden Hour Signature — #F0C840 to #F8A030
Salt & Steel's signature mood lighting. The low-angle sunlight of an hour before sunset, when everything on a ship is bathed in warm gold and shadows are long and amber. This is the game's most recognizable lighting moment and should appear in all key marketing images.

Lighting Philosophy

Natural Light Dominance

Salt & Steel's world is lit by natural sources: sun, moon, fire, and bioluminescence. There are no magical fill lights, no unexplained ambient glow, no convenient illumination that does not have a source. Every lit scene should be explicable: where is the light coming from?

This constraint produces more dramatic and believable lighting than artificial fill. On a ship at sea at night, the only light is the lanterns, the moon, the stars, and the bioluminescence below. This creates genuine darkness with specific, meaningful light pools — the lantern on the quarterdeck creates a circle of amber where the captain stands; the rest of the deck is in varying degrees of moonlit shadow. The visual drama is earned by the constraint.

Golden Hour as Signature

The most iconic Salt & Steel lighting condition: the hour before sunset, when the sun is low and golden, the sea is copper and blue, the ship's sails are lit from the west in amber, and every surface has deep, long shadows. This lighting condition should appear in:

All hero marketing images and key art
The "First Sail" narrative moment
Port arrival sequences at the end of successful voyages
Boss arena entry cinematics where the setting permits

Golden hour is not just beautiful — it is emotionally loaded. The warmth of that light communicates that something was worth the sail, that this moment is significant. It is the game's emotional pitch made visual.

Underwater Filtered Blue-Green

Underwater environments have a completely different lighting character. Sunlight filters through water and becomes:

Directionally caustic — the light moves in wave patterns across surfaces
Color-shifted — reds and oranges are absorbed first, leaving blue-green as the dominant ambient hue
Volumetric — particles in the water scatter light visibly, creating god-rays from the surface

Deeper underwater zones lose the sunlight component and are lit entirely by bioluminescence: the creatures themselves, the algae on rock surfaces, specific minerals that glow faintly. The darkness is more complete but punctuated by vivid specific glows that make these areas feel mysterious rather than merely dark.

Storm Lighting

A storm in Salt & Steel is a lighting event as much as a weather event. The sequence:

Approach: The sky behind the horizon turns storm grey-purple. Sunlight takes on a sickly yellow-green quality (the light filtered through the storm mass ahead). The sea darkens.
Arrival: Cloud cover eliminates the sun. Ambient light goes flat and grey-purple. Lightning creates single frames of harsh white illumination that reveal everything in stark contrast.
Full storm: Torrential rain creates a visual scrim — everything beyond medium range blurs. Lightning is frequent. The ship's lanterns are the primary warm light source, swinging violently.
Eye (if applicable): A sudden, eerie calm. The eye of a hurricane is lit by a circle of sky above — stark sunlight in the middle of darkness.
Aftermath: The storm passes. The sky at the storm's rear edge shows the distinctive Kirby colors: bruised purple and storm grey tearing open to reveal gold and blue beyond. The emotional relief of this transition is the scene's emotional peak.

Environmental Art by Region

The Home Seas

The game's launch region is a composite of tropical and subtropical maritime environments, inspired by the historical Caribbean and the broader Atlantic world during the age of sail.

Visual character: Lush, layered, saturated. Multiple building traditions visible in architecture — centuries of trade and conquest have left physical evidence in how buildings are constructed. Vegetation everywhere — climbing walls, growing through ruins, asserting itself in every gap. The air visually has moisture; heat haze shimmers over rooftops at noon.

Color dominance: Warm. The Home Seas run warm throughout — the blues are warmer (teal not navy), the greens are tropical (vivid, not muted), the browns are sun-baked (golden-brown, not grey-brown). Even shadows here are warm purple-brown, not cold grey.

Key visual landmarks: Plantation ruins with jungle reclaiming them; harbor districts with colorful multi-story buildings in the Kirby palette — every building a different sun-faded color; ancient pre-colonial ruins on high inland ground, covered in carved imagery, half-hidden by centuries of overgrowth.

The Ember Seas

A volcanic region — active geology, geothermal features, black sand beaches, obsidian formations, fumaroles venting steam from the seabed.

Visual character: Dramatic. The Ember Seas are a world of extremes — the deep black of volcanic rock against the vivid orange of lava flows, the electric blue of volcanic lakes, the white of geothermal steam. Nothing is moderate here.

Color dominance: Warm but harsh. Where the Home Seas are warm and welcoming, the Ember Seas are warm and threatening. The dominant colors are volcanic — black, deep orange, ash grey, the particular red-orange of active lava. The sea here is darker, more purple, reflecting the volcanic sky.

Lighting: The Ember Seas have their own light sources beyond the sun: the glow of lava flows visible on distant slopes creates a constant red-orange ambient warmth from inland. At night, active volcanic features act as giant bonfire light sources. Geothermal vents create columns of backlit steam that glow in the ambient heat.

Key visual landmarks: Shipwreck graveyards where vessels caught fire from volcanic ashfall; island chains that are the exposed tops of a submerged volcanic range; ports built on obsidian rock formations, their docks reaching out over boiling water.

Open Sea

The open ocean between major island chains — the most common environment and the one that must be most dynamically realized.

Visual character: Scale. The open sea communicates the smallness of a ship against the world's enormity. The horizon is the dominant visual element: the line where ocean and sky meet, which is always doing something interesting — approaching weather, the haze of a distant island, the particular glitter of sun on water at the horizon.

Dynamic sky system: The sky above the open sea is Salt & Steel's primary real-time rendering achievement. It must express weather states (clear, building, stormy, post-storm) in full dynamic range, with cloud formations that are genuinely beautiful — not grey smears, but architectural cloud structures that the Kirby color palette makes magnificent.

Water rendering: The sea surface must be a living material. In calm conditions: deep blue, slow swells, the mirror-flash of sunlight. In moderate conditions: active chop, spray off wave crests, the turbulence of the ship's wake. In storms: chaotic, dark, violent — waves that block sightlines, spray so dense it creates visual scrim, the chaos of movement in all directions.

Night at sea: Among the game's most distinctive visual conditions. No ambient light except moon and stars. The milky way is genuinely visible — a soft luminous band across the sky. The sea below is dark with phosphorescent bioluminescence appearing at wave crests and in the ship's wake. The ship's lanterns create warm amber pools on deck. This is one of the rarest visual experiences available to a player, and it should feel rare and precious.

Port Cities

Ports are the game's primary social environments — where the player resupplies, recruits crew, receives quests, and engages with the game's political and economic systems. They must feel full — of life, of history, of people going about the business of a maritime civilization.

Visual character: Layered, dense, colorful. Ports in Salt & Steel are built over generations; the visual evidence of that layering is everywhere. Ground floors are old stone. Upper stories are later timber construction. Balconies have been added over windows. Signs hang from every available hook. Laundry dries between buildings. Ships of every size crowd the harbor.

Color: Ports are the most colorful environments in the game. Building facades are painted in local pigments — in tropical ports, these are saturated blues, greens, yellows, and pinks. Awnings stripe the market streets. Flags and pennants hang from every balcony. The visual density of color in a fully populated port should feel overwhelming in the best way — the sensation of being in a place where too much is happening simultaneously.

Time of day transformation: Ports at dawn are grey-blue and quiet, mist on the harbor. Ports at noon are harsh and bright, the sun bleaching color from the highest surfaces. Ports at golden hour are at their most beautiful — the facades glow amber and the harbor water is copper. Ports at night are warm and lamp-lit, the activity shifting to taverns and the dockside. Each time-of-day state is a distinct visual experience.

Underwater Zones

The third dimension of the world — below the surface, accessible through diving mechanics.

Visual character: Otherworldly. Underwater zones are the most visually distinctive content in Salt & Steel. The entire color register shifts: reds and oranges disappear into the blue-green ambient. Caustic light patterns move across every surface. Creatures have the full saturation of actual tropical sea life — which is to say, extraordinary.

Architecture: Underwater ruins have been colonized by marine life. Coral grows over carved stone. Kelp forests occupy the spaces between ruined columns. Every surface is textured with algae, barnacles, sea anemones. The ruins read as old through accumulated biological detail rather than through crumbling.

Creature design: Underwater creatures are where the Kirby principle of grotesque beauty reaches its peak. Sea life is already extraordinary; Salt & Steel's fantastical versions should amplify that extraordinariness. Creatures with bioluminescent markings that shift when they are agitated. Creatures with the Kirby-specific quality of personality — eyes that communicate something, movement that suggests intention.

Light: Described above in the lighting section. The caustic light patterns from surface water are the most important single visual element in underwater zones — they make static environments feel alive.

Shipwrecks

Wrecks are treasure-hunting locations and the repositories of maritime tragedy — the physical remains of ships and their stories.

Visual character: Haunting beauty. Shipwrecks in Salt & Steel should be among the most visually striking content in the game — not grim or decayed, but beautiful in the specific way that things are beautiful when nature has begun to reclaim them. Coral growing on the hull. Fish schooling through the gun ports. Light filtering through the broken deck in shafts.

Narrative through visual archaeology: The story of how a ship was lost should be readable in the physical evidence of the wreck. A ship hit by cannon fire will have specific breach patterns. A ship that burned will have char marks and collapsed structure. A ship that was boarded and taken will have evidence of close combat in the physical state of the decks. The wreck tells a story to an observant player without a word of dialogue.

Character Design Principles

The Kirby Portrait Standard

Every character in Salt & Steel — player character, named NPC, procedurally generated crew member — should be readable as a specific person with a specific history. Not an archetype. Not a demographic placeholder. A person.

The technique for achieving this with procedurally generated characters: contextual feature design. Each feature element in the character generation system carries information about who the character is:

Hands: The specific callusing, scarring, and size of a character's hands communicate their primary occupation before any text description is needed. A gunner's hand has powder burns. A navigator's hand has pen calluses. A brawler's hand has enlarged knuckles.
Posture and bearing: A veteran sailor stands with the slight bow-legged compensation for a lifetime on moving decks. A former military officer stands differently from a self-taught pirate.
Face as biography: Weathering is not random. Sun damage appears on the brow and cheekbones — the places not protected by hats. Scars appear in places where specific injuries are plausible. Wrinkles appear where expression lines develop from years of squinting at horizons.

Cultural Diversity in Design

Salt & Steel's world draws from maritime cultures across the full global range. This must be reflected in character design not as token representation but as genuine visual specificity. Each culture's character designs should be visibly rooted in real aesthetic traditions:

Clothing and textile patterns that reflect actual textile traditions, not generic fantasy robes
Hairstyles, tattoos, jewelry, and personal adornment that are culturally specific
Facial feature diversity that reflects the actual diversity of maritime peoples across the world's oceans

The standard for cultural authenticity: a character from the game's African maritime civilization region should look like someone from a real tradition of African maritime culture, not like a generic fantasy character with darker skin.

Weathered Faces With Stories

The lead player characters — the starting archetypes and their visual options — must look like people who have been places. Not glamour photography models. Not Hollywood-perfect features. People with weather on them, with histories they carry in their posture and their expression.

This does not mean ugly. It means interesting. A face with a healed scar and squint lines around the eyes and salt-chapped lips is more interesting than a face that has never been outside. The player should look at their captain and feel that this person has earned the right to be a captain.

Practical-but-Fantastical Clothing

Clothing in Salt & Steel should be practically motivated — appropriate for life at sea, for the climate of the region, for the occupation of the character — but elevated by the Kirby principle of heightened reality. A sailor's jacket is not a historical reproduction; it is what a sailor's jacket should look like if the world were a Kirby painting. The buttons are more interesting. The weathering tells a better story. The overall silhouette has more presence.

Armor follows the same principle. Light armor is practical — leather, oilcloth, padding — but it is not mundane. The design choices express who the character is, what they value, where they have been. Heavy armor in a maritime world should look like something practical has been made magnificent through craft and aspiration.

Creature Design Principles

Grotesque Beauty

The principle is simple and demanding: every creature in Salt & Steel must have something in it that makes you want to look at it. Not despite its monstrousness — because of it. The sea is full of creatures that are genuinely terrifying and genuinely beautiful, often simultaneously. Salt & Steel's fantastical creatures should aspire to that quality.

Practically, this means:

Color design that is vivid and interesting even on dangerous creatures
Movement that has personality — creatures do not just attack, they move like something
Eyes and facial structure that communicate presence
The specific Kirby quality of biological plausibility pushed just past reality

Faces as Presence

Every creature has a face. In the Kirby principle: not necessarily humanoid, but expressive. The giant squid's mantle should show what it is feeling — expanded when it is agitated, contracted when it is stalking. The sea serpent's eyes should communicate something cold and intelligent. Even the crab-men raiders should have individual expressions readable at medium combat distance.

Scale as Statement

Large creatures in Salt & Steel should feel large — not just geometrically large but experientially large. A sea serpent encounter should create the same feeling that seeing a large whale creates in reality: an almost vertiginous sense of scale, the animal's presence pushing air and water, the realization that you are in the presence of something that does not experience you as significant.

This requires careful design of approach sequences, environmental cues that prime the sense of scale (smaller creatures fleeing, water displacement, shadow), and the specific visual design choices that make a creature read as massive at combat distance.

The Salt & Steel vs. PoE Visual Contrast

For every visual department working on Salt & Steel, this comparison should be on the wall:

Element	PoE	Salt & Steel
Primary mood	Dark, oppressive, precarious	Vibrant, dangerous, wondrous
Color approach	Desaturated, earth tones, restricted palette	Fully saturated, rich, specific associations
Lighting	Torch-dependent, darkness as default	Natural light dominant, golden hour signature
Environments	Decay and corruption as texture	Age and use as texture; nature thriving
Creatures	Anatomical horror, mutated realism	Grotesque beauty, Kirby personality
Characters	Survivors, grimdark, weight	Weathered, specific, larger-than-life
Emotional register	Dread, survival, grim determination	Wonder, danger, exhilaration, grief
Weather	Oppressive, threatening	Dynamic, magnificent, narrative

Both games have weight. Both have danger. Both have characters who feel the cost of what they do. The difference is not between a serious game and a light game — it is between a world that has lost its color and a world that has more color than the real one.

Concept Art to Production Pipeline

The Kirby Test

Every piece of concept art produced for Salt & Steel should be evaluated against a simple question: does this feel like it could have hung in a Kirby exhibition — not in style, but in spirit? Is the color vivid? Does the composition have energy? Does every character and creature in it feel like a specific being? Is there wonder present alongside danger?

This is not a formal checklist — it is an intuition to develop. The art department lead should be able to look at a piece of concept art and know whether it is reaching for the right thing.

Saturated but Not Garish

The single most common failure mode in attempting Kirby-inspired art: pushing saturation into garish territory. Garish means colors without relationship to each other — maximum saturation applied uniformly. Kirby's art was saturated but internally coherent — the colors worked together, grounded in a lighting logic.

The technique: establish the lighting first. Know where the light is coming from and what color it is. Then push saturation within that lighting model. A golden-hour scene can have very high saturation because everything is being lit by rich amber light — the saturation is unified by the light source. An underwater scene can have saturated blue-green because the ambient is specifically blue-green — again, unified.

Material Quality Standards

All surfaces in Salt & Steel must pass the history test: does this surface look like it has been somewhere? New surfaces do not exist in this world. Everything has been touched by salt air, by use, by time. This is different from the PoE standard of decay — it is the standard of use. The ship's railing is worn smooth where hands grip it. The dock is stained by decades of cargo. The tavern floor has the particular deep-clean shine of wood that has been mopped ten thousand times.
