Brand gradient

Postman gradient

The gradient Postman'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). L shifted +0.05 until the ink passes AA at the worst point (4.64:1).

Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 180° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

Report — brand gradient

  • white ink: worst 1.52:1 at 0% (fails AA); black ink: worst 3.53:1 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 high: ~11px bands at 1440px — add grain 24 (≈2% soft-light noise) or shorten the ramp.

mcpConnect your agent — Postman'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.
