# Olympics gradient

Gradients derived from Olympics'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

ΔH 169° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #0081c8 0%, #fcb131 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0081c8] to-[#fcb131]`
- Contrast (worst point): white 1.83:1 fail · black 4.97:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0081c8-fcb131?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). Passes AA for that ink at the worst point (4.93:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklch shorter hue, #617e96 0%, #d7bd9b 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#617e96] to-[#d7bd9b]`
- Contrast (worst point): white 1.80:1 fail · black 4.93:1 AA · banding medium · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.617e96-d7bd9b?a=135&in=oklch&hue=shorter

## 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 −0.10 so white ink passes AA on the surface and both states (worst 4.74:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #006fb4 0%, #005798 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#006fb4] to-[#005798]`
- Contrast (worst point): white 5.34:1 AA · black 2.82:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.006fb4-005798?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #0078be 0%, #0060a4 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #0066aa 0%, #004e8b 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #55baff 0%, #0081c8 50%, #004b87 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#55baff] via-[#0081c8] to-[#004b87]`
- Contrast (worst point): white 2.13:1 fail · black 2.36:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.55baff-0081c8-004b87?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, #0081c8 0%, #008a9f 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0081c8] to-[#008a9f]`
- Contrast (worst point): white 4.07:1 AA-large · black 4.96:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0081c8-008a9f?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, #0081c8 0%, #af6700 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0081c8] to-[#af6700]`
- Contrast (worst point): white 3.84:1 AA-large · black 4.76:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0081c8-af6700?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, #0081c8 0%, #de006b 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0081c8] to-[#de006b]`
- Contrast (worst point): white 4.21:1 AA-large · black 4.30:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0081c8-de006b?a=135

## CSS custom properties (brand.css)

```css

  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #0081c8 0%, #fcb131 100%);
  /* hero — worst-case contrast: white 1.80:1, black 4.93:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #617e96 0%, #d7bd9b 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 5.34:1 AA, black 2.82:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #006fb4 0%, #005798 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #0078be 0%, #0060a4 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #0066aa 0%, #004e8b 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.

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.
