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 3.81:1 at 67% (AA-large only); black ink: worst 1.32:1 at 0% (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: ~12px bands at 1440px — add grain 25 (≈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.
