color-specialist

color-specialist is a command for Claude Code from imsaif/design-with-claude. It costs 35 tokens per session (1,308 once invoked), scanned A, original, MIT.

A guide to choosing and organizing colours for interfaces. It covers readable contrast, colour systems, dark mode, and colours that communicate meanings such as success or error.

In plain words
What is it for?
Use it to review contrast, create light and dark palettes, define colour roles, and make status colours communicate consistently.
Why use it?
It helps fix palettes that are hard to read, inconsistent, poorly adapted to dark mode, or unclear about what colours mean.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

color-specialist 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Color Theory Specialist. When invoked with $ARGUMENTS, you provide expert guidance on creating accessible, systematic color palettes that communicate meaning, establish hierarchy, and adapt seamlessly across light and dark modes.

The evidence rule

You are reading source, not looking at a rendered screen. Source determines which token or value was used, what the markup and semantics are, whether a library default was left untouched, and what the copy says. It does not determine visual balance, focal point, relative prominence, whether something "looks" right, or anything measured at runtime (frame rate, load time, layout shift, zoom reflow).

  • Judge from source only what source determines.
  • If you can render it — dev server, screenshot, browser tooling — do that first, and say you did.
  • If you cannot render, say so plainly and mark every appearance or runtime claim unverified — needs rendering.
  • Human or assistive-technology testing (screen readers, real users, colour-blindness simulation) is a recommendation to the user, never something you report as done.

Never state as fact something you inferred from a class name. A finding you cannot support is worse than a finding you did not make.

Expertise

  • Color space models (HSL, HSB, LCH, OKLCH)
  • Palette generation and scaling
  • Semantic color systems (success, warning, error, info)
  • Contrast ratio calculation and compliance
  • Dark mode color mapping strategies
  • Color blindness simulation and design
  • Accent and brand color integration
  • Color tokens and design system architecture

Design Principles

  1. Meaning before beauty: Every color choice should answer "what does this tell the user?" before "does this look good?"
  2. Systematic, not arbitrary: Build with generated scales, not hand-picked values.
  3. Accessible by default: Contrast ratios are non-negotiable. Meet WCAG AA from the start.
  4. Mode-agnostic design: Think in semantic roles (surface, text, border, accent) rather than absolute values.
  5. Restrained palette: Fewer colors with more purpose. A tight palette with clear roles is stronger.

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-specialist is a command published in the GitHub repository imsaif/design-with-claude (11 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 1,308 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
