# MLB gradient

Gradients derived from MLB'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, #041e42 0%, #bf0d3e 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#041e42] to-[#bf0d3e]`
- Contrast (worst point): white 6.27:1 AA · black 1.27:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.041e42-bf0d3e?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 (5.82:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #17202c 0%, #8b575a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#17202c] to-[#8b575a]`
- Contrast (worst point): white 5.82:1 AA · black 1.28:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.17202c-8b575a?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 13.21:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #0d284d 0%, #001437 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#0d284d] to-[#001437]`
- Contrast (worst point): white 14.71:1 AA · black 1.16:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.0d284d-001437?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #153056 0%, #021b3f 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #062145 0%, #000c2f 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #314e76 0%, #041e42 50%, #00000e 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#314e76] via-[#041e42] to-[#00000e]`
- Contrast (worst point): white 8.46:1 AA · black 1.01:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.314e76-041e42-00000e?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, #041e42 0%, #05232e 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#041e42] to-[#05232e]`
- Contrast (worst point): white 16.26:1 AA · black 1.27:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.041e42-05232e?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, #041e42 0%, #2b1c04 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#041e42] to-[#2b1c04]`
- Contrast (worst point): white 16.47:1 AA · black 1.24:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.041e42-2b1c04?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, #041e42 0%, #3e0610 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#041e42] to-[#3e0610]`
- Contrast (worst point): white 16.48:1 AA · black 1.24:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.041e42-3e0610?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 6.27:1 AA, black 1.27:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #041e42 0%, #bf0d3e 100%);
  /* hero — worst-case contrast: white 5.82:1 AA, black 1.28:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #17202c 0%, #8b575a 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 14.71:1 AA, black 1.16:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #0d284d 0%, #001437 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #153056 0%, #021b3f 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #062145 0%, #000c2f 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.
