# Starlink gradient

Gradients derived from Starlink'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, #27455c 0%, #3860be 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#27455c] to-[#3860be]`
- Contrast (worst point): white 5.86:1 AA · black 2.09:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.27455c-3860be?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 (5.69:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #39434b 0%, #576786 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#39434b] to-[#576786]`
- Contrast (worst point): white 5.69:1 AA · black 2.08:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.39434b-576786?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 7.47:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #325067 0%, #1c3a51 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#325067] to-[#1c3a51]`
- Contrast (worst point): white 8.47:1 AA · black 1.77:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.325067-1c3a51?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #3a5870 0%, #244259 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #2a485f 0%, #153349 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #587891 0%, #27455c 50%, #00172b 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#587891] via-[#27455c] to-[#00172b]`
- Contrast (worst point): white 4.66:1 AA · black 1.16:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.587891-27455c-00172b?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, #27455c 0%, #28474e 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#27455c] to-[#28474e]`
- Contrast (worst point): white 9.94:1 AA · black 2.08:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.27455c-28474e?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, #27455c 0%, #553c25 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#27455c] to-[#553c25]`
- Contrast (worst point): white 9.77:1 AA · black 2.05:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.27455c-553c25?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, #27455c 0%, #672a3d 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#27455c] to-[#672a3d]`
- Contrast (worst point): white 10.00:1 AA · black 1.97:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.27455c-672a3d?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 5.86:1 AA, black 2.09:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #27455c 0%, #3860be 100%);
  /* hero — worst-case contrast: white 5.69:1 AA, black 2.08:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #39434b 0%, #576786 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 8.47:1 AA, black 1.77:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #325067 0%, #1c3a51 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #3a5870 0%, #244259 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #2a485f 0%, #153349 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.
