Under Blue Green
Under Blue Green is a blue gradient from uiGradients (MIT) — #051937 → #004d7a → #008793 → #00bf72 → #a8eb12 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 1.44:1 at 100% (fails AA); black ink: worst 1.20:1 at 0% (fails AA) → use white 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: ~6px bands at 1440px — add grain 12 (≈1% soft-light noise) or shorten the ramp.

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.
