# Lamborghini gradient

Gradients derived from Lamborghini'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, #202020 0%, #29abe2 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#202020] to-[#29abe2]`
- Contrast (worst point): white 2.62:1 fail · black 1.29:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.202020-29abe2?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.14 until the ink passes AA at the worst point (4.59:1).

- CSS: `linear-gradient(135deg in oklab, #050505 0%, #587a8c 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#050505] to-[#587a8c]`
- Contrast (worst point): white 4.59:1 AA · black 1.03:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.050505-587a8c?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 13.01:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #2a2a2a 0%, #171717 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#2a2a2a] to-[#171717]`
- Contrast (worst point): white 14.35:1 AA · black 1.17:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.2a2a2a-171717?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #313131 0%, #1e1e1e 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #222222 0%, #101010 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #4e4e4e 0%, #202020 50%, #010101 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#4e4e4e] via-[#202020] to-[#010101]`
- Contrast (worst point): white 8.32:1 AA · black 1.01:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.4e4e4e-202020-010101?a=135&in=oklch&hue=shorter

## Analogous

Primary #202020 is achromatic — harmony rotates #29abe2 instead. Partner hue from the analogous rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #29abe2 0%, #2ab2bb 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#29abe2] to-[#2ab2bb]`
- Contrast (worst point): white 2.56:1 fail · black 8.00:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.29abe2-2ab2bb?a=135

## Complementary

Primary #202020 is achromatic — harmony rotates #29abe2 instead. 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, #29abe2 0%, #eb7b24 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#29abe2] to-[#eb7b24]`
- Contrast (worst point): white 2.45:1 fail · black 7.39:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.29abe2-eb7b24?a=135&in=oklch&hue=shorter

## Triadic

Primary #202020 is achromatic — harmony rotates #29abe2 instead. Partner hue from the triadic rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #29abe2 0%, #f959ab 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#29abe2] to-[#f959ab]`
- Contrast (worst point): white 2.61:1 fail · black 7.04:1 AA · banding medium

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 2.62:1, black 1.29:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #202020 0%, #29abe2 100%);
  /* hero — worst-case contrast: white 4.59:1 AA, black 1.03:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #050505 0%, #587a8c 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 14.35:1 AA, black 1.17:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #2a2a2a 0%, #171717 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #313131 0%, #1e1e1e 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #222222 0%, #101010 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.

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.
