Neon palette painting: pink, cyan, and sodium yellow done right (and done badly)

Tomasz sent me a Pinterest board last March with forty-seven images on it. Every single one was a cyberpunk character lit by pink and cyan. Forty-seven. I scrolled through it twice and then I wrote him back with a question that I have since started asking on the kickoff call instead of in email: "If everything in your reference is the same two colours, what is the painting going to do differently?"

This piece is about the three-colour neon palette that has eaten cyberpunk illustration, when the discipline of restricting yourself to it makes a portrait sing, and when breaking it is the only thing that saves the piece. The short version: pink, cyan, and sodium yellow are the genre's signature for a reason. They are also why most cyberpunk art looks identical.

The three-colour neon palette, defined

When I say "the cyberpunk neon palette," I mean three specific accent hues that the genre's iconography has settled on across roughly forty years of illustration, film, and game art:

• Neon pink, in the magenta-to-rose family. Hex sits somewhere around #FF2D9C to #FF4FAB. It's the colour of nightclub signage, sex shop windows, and any character who wants to be looked at. It's also the colour of the "tasteful break" that I'll talk about in the cover image discussion of every cyberpunk piece in the studio.
• Cyan, on the electric blue end. Around #00C7E0 to #3DDCEE. The colour of corporate logos, holographic interfaces, and the cold-side rim light in the genre's default lighting setup. It reads as future-tech in a way blue alone doesn't.
• Sodium yellow, the warm streetlamp orange-yellow. Around #F4B838 to #FFA63D. It's the cheapest light source in the world, sodium-vapour streetlamps that have lit every working-class neighbourhood on the planet since the 1960s, and it's the workhorse of the cyberpunk-noir palette. The reason 80s genre photography looks the way it does is sodium streetlamps.

You'll see other accents — saturated red for danger and brand signage, the occasional acid green for hacker-rig overlays, the rare ultraviolet purple for nightclub interiors — but those three are the load-bearing trio. A portrait that uses all three in equal measure looks like every other cyberpunk portrait. A portrait that uses one or two of them deliberately, against a more restrained base, looks like a painting.

Why it works (when it works)

There's a real reason cyberpunk landed on this palette and not, say, the orange-and-teal of action films or the desaturated greys of post-apocalypse work. The three hues are complementary in a useful, slightly unstable way.

Neon pink and cyan sit roughly opposite each other on the colour wheel, which makes them maximally readable when placed together. They generate the highest perceptual contrast a human eye can resolve without going to pure black-and-white. Sodium yellow is the warm relief — when the pink-and-cyan tension gets too cold or too synthetic, sodium light grounds the scene back in something organic. Streetlamp yellow is recognisable as "earth," in a way pure pink isn't.

Three colours, two cold, one warm, complementary tension built in. That's a palette that mathematically can't fail at a glance, which is why every Stable Diffusion default and every Blender tutorial reaches for it the moment "cyberpunk" enters the prompt.

The problem is that "can't fail at a glance" is not the same as "is good." A cyberpunk portrait that uses all three in maximum saturation, with neon signage filling the background and chromatic aberration on every edge, is just every other cyberpunk portrait. The viewer's eye slides off it because it has nothing to land on.

Palette discipline

Here is the rule I've been using on cyberpunk briefs for about a year now, and it has improved every piece since: pick two of the three neon accents, and pick a dominant base that isn't any of them.

The base — the colour that covers sixty to seventy percent of the canvas — should usually be a near-Ink dark (deep blue-blacks, oxidised concrete grey, oil-darkened canvas) or a desaturated mid-tone (rain-grey, dust-warm umber, dead-bulb sodium). The base does the structural work. Then I pick two of the three neons as my accent system.

• Pink and cyan together is the classic cold-and-aggressive register. Best for high-energy portraits, club scenes, rockerboy energy. The sodium streetlight is implied off-frame but not shown.
• Cyan and sodium together is the noir-detective register. Cold tech, warm streetlamp, no pink. Best for fixers, lawmen, anyone whose work happens late at night in functional light.
• Pink and sodium together is the most underused combination and my favourite. Warm-toned, slightly seedy, romantic in a slightly wrong way. Best for characters who are in a city full of corporate cyan but live outside it — nomads who come into town, ex-rockerboys, anyone with a backstory that predates the current corporate regime.

A two-of-three palette gives the painting room to breathe. The third colour can show up as a single tiny detail — a pink earring in an otherwise cyan-and-sodium scene, a cyan reflection in an otherwise pink-and-sodium piece — but it should be one accent, not a whole element. The discipline is what makes the painting feel composed instead of compiled.

A cyberpunk palette of three full-saturation neons reads as a Photoshop default. The same palette restricted to two, with the third as a single placed accent, reads as a deliberate choice.

Mixing neon-pink with warm rim light

This is where most painters lose the piece, and where I lost more than one of my own before I figured it out.

The instinct, when you want neon-pink on a character, is to push the whole side of the face into magenta. Pink rim light, pink ambient fill, pink reflection in the eye, pink on the cheekbone. The result is what I think of as the "fluorescent ham" problem — the character looks like they've been stained with food colouring. Skin reads as plastic. The piece dies at the face, which is where every portrait lives or dies.

The fix is to keep the warm key light warm — true Gold, true sodium-yellow, even a pure Parchment-warm white — and let the neon-pink only touch the silhouette edge of the figure. Not the front plane. Not the cheekbone. Just the thin rim where the figure stops and the background starts.

Mechanically, what this looks like in the painting:

• Warm key light from one side (call it camera-left). Standard portrait light, warm temperature, lighting the front planes of the face.
• Neon-pink rim from the opposite side (camera-right). The pink only catches the edge of the silhouette — the hair, the ear, the jaw line, the shoulder. It never crosses onto the front of the face.
• A cool ambient fill — a desaturated Ink-blue — sits in the shadows where neither the warm key nor the pink rim reaches.
• Skin reads as skin. The pink reads as neon, because it's behaving like neon would in real life: a tube light off-camera, throwing colour onto the edges of things, not the centres.

This is the lighting setup I use on roughly eight out of ten cyberpunk portraits. The Cartographer's Hand brand allows me one neon-pink rim per cyberpunk cover image as the genre accent, and that's why — it's the smallest possible neon presence that still reads as cyberpunk. Restraint is the whole technique.

When to break the rule deliberately

There are two situations where I'll wash a character in full-saturation neon, and they're both deliberate.

The first is the club scene portrait, where the brief is specifically "she is in a nightclub, the painting should be about the colour wash." In that piece, the neon-pink is the environment, not the lighting. It's everywhere because the character is somewhere full of it. The piece reads as immersive instead of looking like a colour mistake, because the brief told you why.

The second is the iconic-moment portrait, where the character is in their signature setting and the colour is the character's signature. A Voodoo Boys netrunner mid-jack with cyan code crawling across her skin. A rockerboy on stage under pink wash. A corpo at her desk in flat cyan office light. In each of those, the colour is doing characterisation, not just decoration.

The rule I'm breaking, in both cases, is "the neon stays on the edges." The reason I'm allowed to break it is that I named the reason in the brief. If the brief doesn't have a stated reason for the neon to flood the whole figure, I keep it to the rim.

The "everything everywhere all at once" anti-pattern

The single most common failure mode in cyberpunk illustration — and the one that makes the genre look exhausted to viewers — is what I call the "everything everywhere all at once" piece. Full neon-pink rim, full cyan ambient, full sodium-yellow backlight, holographic billboards in the background, chromatic aberration on every edge, scanlines layered over the whole image, rain in the foreground, steam in the midground, lens flares from three different sources.

Each element on its own is a legitimate cyberpunk technique. All of them at once is visual noise. The viewer's eye has nowhere to rest, no hierarchy, no focal point. The piece reads as "cyberpunk" the way a stock-photo Halloween costume reads as "scary."

What separates a strong cyberpunk portrait from a busy one is subtractive composition. Pick one neon accent. Pick one atmospheric element. Pick one background read. Pick one surface treatment. The piece is allowed to have those four things working together. It is not allowed to have all of them in one painting.

When I'm reviewing my own thumbnails, I run a simple test: if I cover the figure with my thumb, can I tell where the painting is supposed to be? If yes, the background is doing too much. If I cover the background, can I read the character? If no, the figure isn't doing enough on its own. A good cyberpunk portrait passes both halves.

The CRT scanlines when they work sibling piece goes deeper on the surface-treatment side of this — when the scanline-and-chromatic-aberration aesthetic earns its place and when it just looks dated.

A short colour-comp workflow

Here's the workflow I use at the colour-comp stage of every cyberpunk piece, which is the stage I block out the palette before any rendering happens.

1. Base value pass first. I paint the whole composition in monochrome — warm-grey or cool-grey, your choice — and lock the value structure. Light, mid, dark, where the eye goes. If the painting works in monochrome, it'll work in colour. If it doesn't, no palette will save it.
2. Pick the base hue. Usually an Ink-dark or a desaturated mid-grey. This is the canvas the neon sits on. Cover sixty percent of the painting in it.
3. Add the warm key. Warm key light on the figure, sodium-yellow or true Gold, single direction. The character's front planes live here.
4. Add one neon rim. Pink, cyan, or sodium-warm — pick one. Apply it only to the silhouette edge opposite the key.
5. Add one tiny accent of a third colour. A single specular highlight, a piece of clothing trim, a glowing screen reflection in an eye. One placed touch of the third hue, no bigger than a thumbnail-pixel in the final composition.
6. Stop. Resist the urge to add a second neon rim, a second accent, a third background colour. The piece is done as a colour comp. Render from here.

I learned this workflow the hard way on a commission for Sera, a netrunner portrait that I overpainted three times before I got it right. The fourth pass had the same composition as the first, but only two-thirds the colour. It shipped. She framed it. The other three are in a folder labelled "too much."

Where to take the brief next

If you've got a cyberpunk character whose visual language is "neon" but you're not sure which neon, the order form has a free-text field where you can describe the lighting register in one or two sentences. I'd rather have "she lives in pink and sodium light, no cyan" than a board of forty-seven images. The portfolio has the painted versions of the palette discipline I've described, filed under cyberpunk.

For more on the surrounding craft, the cyberpunk character art commission guide sits one level up. The cybernetic limb and face design references sibling covers chrome rendering, which interacts heavily with the palette discussion above. The street samurai vs netrunner vs corpo breakdown shows how archetype determines which two of the three neons fit. The character art process sketch color final evergreen walks through where the colour-comp stage fits into the bigger workflow.

Pick two of three. Save the third for the single placed accent. The piece will thank you.
