Use when building a design token system, creating accessible colour palettes, generating colour ramps programmatically, or migrating a design system to support wide-gamut displays.
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
# Use oklch() and oklab() for perceptually uniform colour palettes HSL and hex colours are defined in the sRGB colour space, which is not perceptually uniform — a 10 % lightness change looks dramatically different depending on the hue. This makes creating accessible, harmonious palettes by hand extremely difficult. oklch corrects this: adjusting the L channel produces the same perceived brightness change regardless of hue or chroma, making it far easier to build accessible colour ramps, dark-mode palettes, and consistent hover/active states. ## Quick Reference - oklch(L C H) — Lightness, Chroma, Hue — is the most practical perceptually uniform colour space for design systems - Equal lightness steps in oklch look equal to the human eye; equal steps in hsl do not - Define your colour palette tokens in oklch custom properties - Use @media (color-gamut: p3) to serve wide-gamut colours to capable displays ## Check Check whether the CSS colour tokens use oklch() or a perceptually uniform colour space, or whether they use hsl/hex which may produce inconsistent perceived lightness across hues. ## Fix …

How to install
mdr add thedaviddias/front-end-checklist/color-oklch@sha256:4b4d3b5897bfdc57The line at the top of this page pins the label git:20261004.4b0ddb9, 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.
