# Pinterest gradient

Gradients derived from Pinterest's published colour tokens (nominative use; no brand assets). Deterministic: the same values are served as `--brand-gradient*` in the brand's brand.css.

## Brand gradient

ΔE_OK 0.019 < 0.15 between #e40424 and #dd0e0e — a 2-stop would read as a flat fill, so this is a tonal ramp of #e40424.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff8178 0%, #e40424 50%, #910003 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff8178] via-[#e40424] to-[#910003]`
- Contrast (worst point): white 2.42:1 fail · black 2.21:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff8178-e40424-910003?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.18 until the ink passes AA at the worst point (4.62:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #966a65 0%, #6f312b 50%, #32080e 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#966a65] via-[#6f312b] to-[#32080e]`
- Contrast (worst point): white 4.62:1 AA · black 1.18:1 fail · banding high · ink #ffffff

## Button / CTA

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 −0.06 so white ink passes AA on the surface and both states (worst 4.63:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #dd001d 0%, #b8000a 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#dd001d] to-[#b8000a]`
- Contrast (worst point): white 5.13:1 AA · black 3.04:1 AA-large · banding high · ink #ffffff

- Hover: `linear-gradient(180deg in oklch shorter hue, #e81028 0%, #c7000d 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff8178 0%, #e40424 50%, #910003 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff8178] via-[#e40424] to-[#910003]`
- Contrast (worst point): white 2.42:1 fail · black 2.21:1 fail · banding high

## Analogous

Partner hue from the analogous rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #e40424 0%, #da0480 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#e40424] to-[#da0480]`
- Contrast (worst point): white 4.82:1 AA · black 4.30:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.e40424-da0480?a=135

## 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.

- CSS: `linear-gradient(135deg in oklch shorter hue, #e40424 0%, #038a96 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#e40424] to-[#038a96]`
- Contrast (worst point): white 4.11:1 AA-large · black 4.33:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.e40424-038a96?a=135&in=oklch&hue=shorter

## Triadic

Partner hue from the triadic rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #e40424 0%, #03942b 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#e40424] to-[#03942b]`
- Contrast (worst point): white 3.96:1 AA-large · black 4.33:1 AA-large · banding medium

## CSS custom properties (brand.css)

```css

  /* Brand gradient (derived) */

  /* button — worst-case contrast: white 5.13:1 AA, black 3.04:1 AA-large */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #dd001d 0%, #b8000a 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #e81028 0%, #c7000d 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #d1000f 0%, #a90007 100%);

## Gradient maker

Every maker URL is the gradient's state: `/gradients/new/v1.<hex>-<hex>[_pos]?a=135&in=oklch&hue=shorter&e=soft&g=8`. Hand one to a human, let them refine, and read the link they return.
