# FIFA gradient

Gradients derived from FIFA'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, #102139 0%, #326295 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#102139] to-[#326295]`
- Contrast (worst point): white 6.33:1 AA · black 1.30:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.102139-326295?a=135

## 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 (6.33:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #1b212a 0%, #526173 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#1b212a] to-[#526173]`
- Contrast (worst point): white 6.33:1 AA · black 1.30:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1b212a-526173?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. White ink passes AA on the surface and both states (worst 12.79:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #192b44 0%, #07172f 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#192b44] to-[#07172f]`
- Contrast (worst point): white 14.28:1 AA · black 1.17:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.192b44-07172f?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #21334c 0%, #0e1f36 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #12233c 0%, #031027 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #3d506b 0%, #102139 50%, #00000c 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#3d506b] via-[#102139] to-[#00000c]`
- Contrast (worst point): white 8.21:1 AA · black 1.00:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.3d506b-102139-00000c?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, #102139 0%, #12242b 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#102139] to-[#12242b]`
- Contrast (worst point): white 15.94:1 AA · black 1.29:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.102139-12242b?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, #102139 0%, #291f10 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#102139] to-[#291f10]`
- Contrast (worst point): white 16.13:1 AA · black 1.28:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.102139-291f10?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, #102139 0%, #381417 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#102139] to-[#381417]`
- Contrast (worst point): white 16.10:1 AA · black 1.28:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.102139-381417?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 6.33:1 AA, black 1.30:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #102139 0%, #326295 100%);
  /* hero — worst-case contrast: white 6.33:1 AA, black 1.30:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #1b212a 0%, #526173 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 14.28:1 AA, black 1.17:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #192b44 0%, #07172f 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #21334c 0%, #0e1f36 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #12233c 0%, #031027 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.
