Unicorn Rainbow

Unicorn Rainbow is a yellow gradient from uiGradients (MIT) — #f7f0ac → #acf7f0 → #f0acf7 at 90°. Shown here interpolated in OKLab, next to the original sRGB, with the worst-case contrast for white and black text and every export.

Same stops, three spaces

The source renders this in sRGB. The number is how much chroma survives at the dullest point along the line — the difference between the first bar and the others is the grey that OKLab removes.

Report

  • white ink: worst 1.17:1 at 3% (fails AA); black ink: worst 11.95:1 at 100% (AA) → use black text.
  • Banding high: ~10px bands at 1440px — add grain 20 (≈2% soft-light noise) or shorten the ramp.

mcpConnect your agent to the gradient engine
live endpoint

Point any MCP client at the shared gradients endpoint and your agent gets the same engine as this page — make_gradient returns CSS with the interpolation space, Tailwind v4, SVG, a PNG URL, a DTCG token and the contrast report in one call; brand_gradients derives the whole contact sheet from a brand or a palette. Read-only, no key. Every gradient is a /gradients/new/… link: open it, refine, paste it back.
