Brand gradient

Formula 1 gradient

The gradient Formula 1'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.

ΔL 0.08 top→bottom in the primary's hue (a lit surface, not a rainbow); hover L +0.03, active L −0.03. Black ink passes AA on the surface and both states (worst 11.96:1).

Report — brand gradient

white ink: worst 1.40:1 at 0% (fails AA); black ink: worst 4.23:1 at 100% (AA-large only) → use black 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 medium: ~6px bands at 1440px — add grain 11 (≈1% soft-light noise) or shorten the ramp.
26/64 samples left sRGB by more than 5% and were gamut-mapped (oklch shorter); expect slight hue drift there.

mcpConnect your agent — Formula 1'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.
