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 3.87:1 at 0% (AA-large only); black ink: worst 2.20:1 at 100% (fails AA) → use white 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 high: ~17px bands at 1440px — add grain 34 (≈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.
