# Oatly gradient

Gradients derived from Oatly'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

- CSS: `linear-gradient(135deg in oklab, #a0632d 0%, #fdcf85 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#a0632d] to-[#fdcf85]`
- Contrast (worst point): white 1.45:1 fail · black 4.32:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.a0632d-fdcf85?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). L shifted +0.01 until the ink passes AA at the worst point (4.61:1).

- CSS: `linear-gradient(135deg in oklab, #877261 0%, #e8d8bf 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#877261] to-[#e8d8bf]`
- Contrast (worst point): white 1.40:1 fail · black 4.61:1 AA · banding medium · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.877261-e8d8bf?a=135

## 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 4.67:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #9a5d27 0%, #814606 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#9a5d27] to-[#814606]`
- Contrast (worst point): white 5.29:1 AA · black 2.81:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.9a5d27-814606?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #a36630 0%, #8a4f15 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #90541c 0%, #773e00 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #db9964 0%, #a0632d 50%, #683000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#db9964] via-[#a0632d] to-[#683000]`
- Contrast (worst point): white 2.40:1 fail · black 2.01:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.db9964-a0632d-683000?a=135&in=oklch&hue=shorter

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #a0632d 0%, #c73a2d 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#a0632d] to-[#c73a2d]`
- Contrast (worst point): white 4.84:1 AA · black 4.06:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.a0632d-c73a2d?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, #a0632d 0%, #317ba8 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#a0632d] to-[#317ba8]`
- Contrast (worst point): white 4.42:1 AA-large · black 4.29:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.a0632d-317ba8?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, #a0632d 0%, #338375 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#a0632d] to-[#338375]`
- Contrast (worst point): white 4.50:1 AA · black 4.30:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.a0632d-338375?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.45:1, black 4.32:1 AA-large */
  --brand-gradient: linear-gradient(135deg in oklab, #a0632d 0%, #fdcf85 100%);
  /* hero — worst-case contrast: white 1.40:1, black 4.61:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #877261 0%, #e8d8bf 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 5.29:1 AA, black 2.81:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #9a5d27 0%, #814606 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #a36630 0%, #8a4f15 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #90541c 0%, #773e00 100%);
  --brand-gradient-button-ink: #ffffff;
}
```

## 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.

## Connect an agent

Point any MCP client at the BrandSweets gradients endpoint for the same engine and corpus:

- Endpoint: https://mcp.brandsweets.com/gradients/mcp
- Tools: `make_gradient` (2–5 colours → CSS with the interpolation space, Tailwind v4, SVG, PNG URL, DTCG token + the contrast/banding/gamut report), `brand_gradients` (brand slug or palette → brand gradient, hero, button, variants).
- Resource: `gradients://corpus` — the whole bundled corpus as JSON.
