Brand gradient

Auth0 gradient

The gradient Auth0'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 white (inkFor at the midpoint). L shifted −0.02 until the ink passes AA at the worst point (4.69:1).

ΔL 0.08 top→bottom in the primary's hue (a lit surface, not a rainbow); hover L +0.03, active L −0.03. L shifted −0.09 so white ink passes AA on the surface and both states (worst 4.62:1).

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 4.26:1 at 1% (AA-large only); black ink: worst 2.09:1 at 100% (fails AA) → use white 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: ~18px bands at 1440px — add grain 36 (≈2% soft-light noise) or shorten the ramp.

mcpConnect your agent — Auth0'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.
