# Hasbro gradient

Gradients derived from Hasbro'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, #003c69 0%, #005eb8 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#003c69] to-[#005eb8]`
- Contrast (worst point): white 6.38:1 AA · black 1.85:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.003c69-005eb8?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 (6.27:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #2d3c4b 0%, #4a6280 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#2d3c4b] to-[#4a6280]`
- Contrast (worst point): white 6.27:1 AA · black 1.86:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.2d3c4b-4a6280?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 8.52:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #104775 0%, #00315d 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#104775] to-[#00315d]`
- Contrast (worst point): white 9.63:1 AA · black 1.60:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.104775-00315d?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #1a4f7e 0%, #003966 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #033f6c 0%, #002954 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #3b6fa0 0%, #003c69 50%, #000d31 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#3b6fa0] via-[#003c69] to-[#000d31]`
- Contrast (worst point): white 5.29:1 AA · black 1.10:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.3b6fa0-003c69-000d31?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, #003c69 0%, #004250 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#003c69] to-[#004250]`
- Contrast (worst point): white 11.03:1 AA · black 1.84:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.003c69-004250?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, #003c69 0%, #533100 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#003c69] to-[#533100]`
- Contrast (worst point): white 11.31:1 AA · black 1.76:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.003c69-533100?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, #003c69 0%, #70002b 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#003c69] to-[#70002b]`
- Contrast (worst point): white 11.30:1 AA · black 1.72:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.003c69-70002b?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 6.38:1 AA, black 1.85:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #003c69 0%, #005eb8 100%);
  /* hero — worst-case contrast: white 6.27:1 AA, black 1.86:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #2d3c4b 0%, #4a6280 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 9.63:1 AA, black 1.60:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #104775 0%, #00315d 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #1a4f7e 0%, #003966 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #033f6c 0%, #002954 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.
