Brand gradient

WhatsApp gradient

The gradient WhatsApp'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.

Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). Passes AA for that ink at the worst point (8.61:1) without adjusting L.

ΔL 0.08 top→bottom in the primary's hue (a lit surface, not a rainbow); hover L +0.03, active L −0.03. White ink passes AA on the surface and both states (worst 13.43:1).

Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 174° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

Report — brand gradient

  • white ink: worst 8.64:1 at 0% (AA); black ink: worst 1.00:1 at 98% (fails AA) → use white text.
  • Black text disappears completely at 98% (1.00:1 crossing).
  • Banding high: ~23px bands at 1440px — add grain 43 (≈3% soft-light noise) or shorten the ramp.

mcpConnect your agent — WhatsApp'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.
