Report

  • white ink: worst 2.28:1 at 100% (fails AA); black ink: worst 6.79:1 at 0% (AA) → use black text.
  • Banding high: ~23px bands at 1440px — add grain 43 (≈3% 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.
