Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Color Operations Practical color knowledge for developers and designers. Covers color spaces, accessibility, palette generation, CSS implementation, and design token architecture. > Inspired by [meodai/skill.color-expert](https://github.com/meodai/skill.color-expert) - a comprehensive 286K-word color science knowledge base with 113 reference files. This is a lightweight operational skill for everyday frontend and design work. For deep color science (spectral mixing, historical color theory, CAM16, pigment physics), install the full skill. ## Color Space Decision Table Pick the right space for the task. This is the single most impactful color decision you'll make. | Task | Use | Why | |------|-----|-----| | Perceptual color manipulation | **OKLCH** | Best uniformity for lightness, chroma, hue | | CSS gradients & palettes | **OKLCH** or `color-mix(in oklab)` | No mid-gradient grey/brown deadzone | | Gamut-aware color picking | **OKHSL / OKHSV** | Cylindrical like HSL but perceptually grounded | | Normalized saturation (0-100%) | **HSLuv** | CIELUV chroma normalized per hue/lightness | | Print workflows | **CIELAB D50** | ICC standard illuminant | …

How to install
mdr add 0xdarkmatter/claude-mods/color-ops@sha256:e8196eb83f359734The line at the top of this page pins the label git:20260708.e0b865f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
