Brand gradient

Supabase gradient

The gradient Supabase's published colour tokens imply, derived by a pure function of the palette: primary → secondary in OKLab (OKLCH shorter hue when the hues are more than 140° apart; a tonal ramp when they are within ΔE 0.15), then a hero background with an ink that passes AA at the worst point along the line, a button surface with hover and active states, and the variant contact sheet. Same inputs, same gradients, forever — which is what makes them citable; the same values are served as --brand-gradient in the brand's brand.css.

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). Passes AA for that ink at the worst point (5.20:1) without adjusting L.

Report — brand gradient

white ink: worst 1.19:1 at 0% (fails AA); black ink: worst 5.44:1 at 100% (AA) → use black text.
Banding high: ~12px bands at 1440px — add grain 24 (≈2% soft-light noise) or shorten the ramp.

mcpConnect your agent — Supabase's gradients on demand

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.
