Chitty Chitty Bang Bang is a blue gradient from uiGradients (MIT) — #007991 → #78ffd6 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 1.23:1 at 100% (fails AA); black ink: worst 4.14:1 at 0% (AA-large only) → use black text.
  • Body text fails AA everywhere on this gradient; large text (≥24px / 19px bold) is fine. Add a scrim or lower the chroma for body copy.
  • Banding medium: ~11px bands at 1440px — add grain 22 (≈2% soft-light noise) or shorten the ramp.

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.
