color-expert

Catalogue stub — full skill: meodai/skill.color-expert

<!-- das:install:start — generated from stub.yaml by `npm run generate`; edit stub.yaml, not this block -->

Decision tree

  1. Is the full skill already installed?
    • Global: f=~/.agents/skills/color-expert/SKILL.md; [ -f "$f" ] && ! grep -q "^das:" "$f" && echo "installed" || echo "pointer"
    • Project: f=.agents/skills/color-expert/SKILL.md; [ -f "$f" ] && ! grep -q "^das:" "$f" && echo "installed" || echo "pointer"
    • installed → the skill is installed as color-expert, invoke it and proceed
    • pointer → go to step 2

  2. Detect scope, then install:

    [ -e ~/.agents/skills/color-expert ] && echo "global" || echo "project"

    Global:

    npx skills add meodai/skill.color-expert --skill color-expert -g -y

    Project:

    npx skills add meodai/skill.color-expert --skill color-expert -y

    Claude Code: send a command as a chat message starting with ! to run it without leaving the conversation.

Heads-up

Invoke after install

  • Skill name: color-expert
  • Trigger phrases: "color expert", "OKLCH", "color palette", "color science", "contrast ratio"

What it does

Brings a deep color-science reference library into design decisions: the skill file carries the essentials and an index points into hundreds of reference files. Covers perceptually uniform color spaces (OKLCH, OKLAB), palette generation algorithms, WCAG accessibility contrast, color naming conventions, pigment mixing theory, CSS color syntax, and the history of color in art and design. Ideal for building color systems, choosing palettes with correct contrast, or understanding why certain color combinations feel wrong.

When NOT to use

  • Design-token file structure (DTCG, aliasing, theme resolvers) → use design-tokens-skill
  • A full accessibility audit (WCAG beyond contrast) → use wcag-audit-patterns or addyosmani-quality

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
