# Xbox gradient

Gradients derived from Xbox'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, #147c14 0%, #0067b8 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#147c14] to-[#0067b8]`
- Contrast (worst point): white 5.33:1 AA · black 3.62:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.147c14-0067b8?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 (5.56:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #536f51 0%, #506884 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#536f51] to-[#506884]`
- Contrast (worst point): white 5.56:1 AA · black 3.64:1 AA-large · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.536f51-506884?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 −0.04 so white ink passes AA on the surface and both states (worst 4.73:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #147c14 0%, #006400 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#147c14] to-[#006400]`
- Contrast (worst point): white 5.35:1 AA · black 2.82:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.147c14-006400?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #228520 0%, #006d00 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #007303 0%, #005b00 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #57b452 0%, #147c14 50%, #004500 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#57b452] via-[#147c14] to-[#004500]`
- Contrast (worst point): white 2.61:1 fail · black 1.85:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.57b452-147c14-004500?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, #147c14 0%, #686c0f 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#147c14] to-[#686c0f]`
- Contrast (worst point): white 5.33:1 AA · black 3.73:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.147c14-686c0f?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, #147c14 0%, #9f15b0 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#147c14] to-[#9f15b0]`
- Contrast (worst point): white 5.33:1 AA · black 3.20:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.147c14-9f15b0?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, #147c14 0%, #0a52ec 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#147c14] to-[#0a52ec]`
- Contrast (worst point): white 5.32:1 AA · black 3.43:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.147c14-0a52ec?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 5.33:1 AA, black 3.62:1 AA-large */
  --brand-gradient: linear-gradient(135deg in oklab, #147c14 0%, #0067b8 100%);
  /* hero — worst-case contrast: white 5.56:1 AA, black 3.64:1 AA-large; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #536f51 0%, #506884 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 5.35:1 AA, black 2.82:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #147c14 0%, #006400 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #228520 0%, #006d00 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #007303 0%, #005b00 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.
