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 1.43:1 at 100% (fails AA); black ink: worst 1.58:1 at 0% (fails AA) → use black text.
  • Neither ink passes AA at the worst point — treat as decorative or add a scrim (rgba(0,0,0,.35) typically lifts white ink past 4:1).
  • Banding medium: ~7px bands at 1440px — add grain 12 (≈1% 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.
