# Prime Video gradient

Gradients derived from Prime Video'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 154° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffd62c 0%, #79b8f3 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffd62c] to-[#79b8f3]`
- Contrast (worst point): white 1.41:1 fail · black 9.96:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ffd62c-79b8f3?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 (9.95:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklch shorter hue, #e6d9ad 0%, #a0b5c9 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#e6d9ad] to-[#a0b5c9]`
- Contrast (worst point): white 1.41:1 fail · black 9.95:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.e6d9ad-a0b5c9?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. Black ink passes AA on the surface and both states (worst 11.88:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #ffe341 0%, #f2c908 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ffe341] to-[#f2c908]`
- Contrast (worst point): white 1.29:1 fail · black 13.13:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.ffe341-f2c908?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #ffef85 0%, #fcd326 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #ffd932 0%, #e8bf00 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #fff8ae 0%, #ffd62c 50%, #c29c00 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fff8ae] via-[#ffd62c] to-[#c29c00]`
- Contrast (worst point): white 1.09:1 fail · black 8.05:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fff8ae-ffd62c-c29c00?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, #ffd62c 0%, #ffcfa3 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ffd62c] to-[#ffcfa3]`
- Contrast (worst point): white 1.41:1 fail · black 14.68:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ffd62c-ffcfa3?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 179° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffd62c 0%, #cdd8ff 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffd62c] to-[#cdd8ff]`
- Contrast (worst point): white 1.34:1 fail · black 14.82:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ffd62c-cdd8ff?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, #ffd62c 0%, #8deaff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ffd62c] to-[#8deaff]`
- Contrast (worst point): white 1.36:1 fail · black 14.88:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ffd62c-8deaff?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.41:1, black 9.96:1 AA */
  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #ffd62c 0%, #79b8f3 100%);
  /* hero — worst-case contrast: white 1.41:1, black 9.95:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #e6d9ad 0%, #a0b5c9 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 1.29:1, black 13.13:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #ffe341 0%, #f2c908 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #ffef85 0%, #fcd326 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #ffd932 0%, #e8bf00 100%);
  --brand-gradient-button-ink: #000000;
}
```

## 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.
