Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00119 | $0.00574 |
| Opus 5.5 | $0.00048 | $0.00230 |
| Sonnet 5.5 | $0.00024 | $0.00115 |
| Haiku 4.5 | $0.00012 | $0.00057 |
Grade A, and why
color scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Color
Color decisions in this package are made in OKLCH (perceptual lightness L, chroma C, hue H), not hex or HSL, because equal numeric steps in OKLCH are equal perceived steps — which is what makes ramps even, themes coherent, and contrast predictable. Hex is only an output format.
Workflow
- Read the design philosophy (from
design-direction); the palette's emotional register comes from there, not from this skill. - Construct the palette in OKLCH using references/palette-construction.md — anchor hue → neutral ramp (tinted, never pure grey) → accent ramp → semantic colors.
- If the work has themes, build dark and light as sibling palettes, not inversions, per references/themes.md.
- Verify every text/background pair against references/contrast-and-restraint.md before shipping; it also covers when glow/saturation is earned vs. noise.
Which reference to load
| Situation | Load |
|---|---|
| OKLCH mechanics, converting, browser/tool support | references/oklch-foundations.md |
| Building a palette, ramps, data-viz series colors | references/palette-construction.md |
| Dark mode, theme families, elevation in dark UIs | references/themes.md |
| Contrast checking, WCAG/APCA, glow & saturation discipline | references/contrast-and-restraint.md |
Non-negotiables
- Body text meets WCAG AA (4.5:1) minimum; UI chrome ≥ 3:1. Check, don't eyeball.
- Neutrals carry a trace of the anchor hue (C ≈ 0.005–0.02). Pure grey reads dead.
- One color is the loudest in any view. If two compete, demote one.
- Never ship a palette without rendering it in the real artifact and running the
critiqueskill on the result.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

color is a skill published in the GitHub repository jangles-byte/atelier (3 stars, last pushed 2mo ago), licensed MIT. It adds 119 tokens to every session and 574 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
