What it does

Color Expert is an agent skill from meodai/skill.color-expert. Use when working with color naming, color theory, color spaces, color definitions, or any task involving color knowledge - palettes, ramps, gradients, conversions, accessibility, perceptual matching, pigment mixing, print-vs-screen color, CSS color syntax, or historical color terminology. Use this skill whenever the user is choosing, comparing, generating, naming, converting, or explaining colors, even if they do not explicitly ask for "color theory."

Its SKILL.md is about 8.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 207 other files, including scripts and reference files (for example `CLAUDE.md`, `MAINTENANCE.md` and `README.md`).

It sits in Frontend & Design, covering Accessibility. It works with OpenAI. The repository describes itself as: Agent skill for color science expertise. Many references covering color spaces, accessibility (APCA, WCAG), palette generation, pigment mixing, and historical color theory. Works…

When your agent uses it

  • Working with color naming
  • Color definitions
  • Any task involving color knowledge - palettes
  • Perceptual matching

Example prompts

  • “color theory.”
  • “/color-expert”

What it can do on your machine

Read from SKILL.md and the folder at commit 29188b2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/, which the agent can run.

    Shell commands in SKILL.md call:

    • npm
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Color Expert loads about 8.9k tokens when it runs, and up to ~626k if it reads all its reference files. Until then it costs about 117 tokens; SKILL.md has 4,374 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~117
When it runs · the whole SKILL.md, loaded when a task matches
~8.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~626k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 4,374 words (~8,890 tokens).

“A comprehensive knowledge base for color-related work. See references/INDEX.md for a one-line-per-file map of 180+ reference files; this skill file contains the essential knowledge to answer most questions directly.”
