# Airbus gradient

Gradients derived from Airbus'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, #070b11 0%, #00205b 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#070b11] to-[#00205b]`
- Contrast (worst point): white 15.47:1 AA · black 1.06:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.070b11-00205b?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 (15.19:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #090b0d 0%, #1b2639 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#090b0d] to-[#1b2639]`
- Contrast (worst point): white 15.19:1 AA · black 1.06:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.090b0d-1b2639?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 17.44:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #0f141a 0%, #020408 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#0f141a] to-[#020408]`
- Contrast (worst point): white 18.50:1 AA · black 1.02:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.0f141a-020408?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #161a21 0%, #05090f 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #090d13 0%, #010204 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #30353d 0%, #070b11 50%, #000002 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#30353d] via-[#070b11] to-[#000002]`
- Contrast (worst point): white 12.34:1 AA · black 1.00:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.30353d-070b11-000002?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, #070b11 0%, #070b0d 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#070b11] to-[#070b0d]`
- Contrast (worst point): white 19.72:1 AA · black 1.06:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.070b11-070b0d?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 173° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #070b11 0%, #0d0a07 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#070b11] to-[#0d0a07]`
- Contrast (worst point): white 19.69:1 AA · black 1.06:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.070b11-0d0a07?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, #070b11 0%, #110808 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#070b11] to-[#110808]`
- Contrast (worst point): white 19.68:1 AA · black 1.06:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.070b11-110808?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 15.47:1 AA, black 1.06:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #070b11 0%, #00205b 100%);
  /* hero — worst-case contrast: white 15.19:1 AA, black 1.06:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #090b0d 0%, #1b2639 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 18.50:1 AA, black 1.02:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #0f141a 0%, #020408 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #161a21 0%, #05090f 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #090d13 0%, #010204 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.
