Allison — Accessible Color Palettes

About this plugin

Allison — the FREE accessible color ramp generator that shows its work.Type one hex color, and Allison (a11y-son, get it?) detects which Tailwind-style shade (50–900) it
reads as, then builds the rest of the ramp around it so every step hits an exact,
guaranteed contrast target — not an approximation. Review the full pairwise
contrast grid under WCAG AA/AAA and APCA side by side, tweak the base color live
with instant re-solving, art-direct the chroma curve by hand if you want to
deviate from the automated gamut-based default, and commit straight to Figma
variables — including overwriting an existing collection in place, so bound
layers update instantly. Built by Verhaert, free forever.
