color-expert

color-expert is a color science expert skill backed by 286K words of reference material covering OKLCH/OKLAB color spaces, palette generation, accessibility and contrast, color naming, pigment mixing, and historical color theory. It is a curated Open Design catalogue entry (curated from @meodai) that advertises the skill so an agent can discover it during planning when color-related work comes up, then run the underlying color-science workflow.

Because it is a catalogue entry, the skill's role in Open Design is primarily discovery: it exposes the skill's capabilities and trigger phrases so the agent surfaces it at the right moment. Its declared triggers include "color theory", "palette generator", "color science", "oklch palette", and "contrast check", and it is categorized under design-systems (mode design-system). To run the full upstream workflow with its original assets, scripts, and references, the user installs the upstream bundle from https://github.com/meodai/skill.color-expert into the active agent's skills directory, inspecting the upstream README for exact paths. After installation the agent can invoke the skill by name (color-expert) or via one of the trigger phrases in the frontmatter.

color-expert targets designers and developers working on design systems who need authoritative help with modern color work, such as building OKLCH/OKLAB palettes, checking contrast for accessibility, naming colors, reasoning about pigment mixing, or drawing on historical color theory. The catalogue entry itself is a lightweight advertisement; the substantive reference material and any scripts live in the upstream repository, so the practical requirement is installing that upstream bundle to access the complete workflow.
