# Hugging Face gradient

Gradients derived from Hugging Face'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

No secondary or accent — the second stop is derived (analogous +30° at the primary's lightness).

- CSS: `linear-gradient(135deg in oklab, #0b0f19 0%, #100e16 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0b0f19] to-[#100e16]`
- Contrast (worst point): white 19.09:1 AA · black 1.09:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0b0f19-100e16?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 (19.11:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #0e0f13 0%, #100f12 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0e0f13] to-[#100f12]`
- Contrast (worst point): white 19.11:1 AA · black 1.10:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.0e0f13-100f12?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 16.49:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #141822 0%, #040710 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#141822] to-[#040710]`
- Contrast (worst point): white 17.74:1 AA · black 1.04:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.141822-040710?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #1a1f2a 0%, #090d17 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #0d111b 0%, #020309 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #353a46 0%, #0b0f19 50%, #000002 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#353a46] via-[#0b0f19] to-[#000002]`
- Contrast (worst point): white 11.38:1 AA · black 1.00:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.353a46-0b0f19-000002?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, #0b0f19 0%, #0c1012 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0b0f19] to-[#0c1012]`
- Contrast (worst point): white 19.08:1 AA · black 1.09:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0b0f19-0c1012?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 171° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #0b0f19 0%, #110f0c 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0b0f19] to-[#110f0c]`
- Contrast (worst point): white 19.10:1 AA · black 1.09:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0b0f19-110f0c?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, #0b0f19 0%, #150d0c 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0b0f19] to-[#150d0c]`
- Contrast (worst point): white 19.10:1 AA · black 1.09:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0b0f19-150d0c?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 19.09:1 AA, black 1.09:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #0b0f19 0%, #100e16 100%);
  /* hero — worst-case contrast: white 19.11:1 AA, black 1.10:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #0e0f13 0%, #100f12 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 17.74:1 AA, black 1.04:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #141822 0%, #040710 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #1a1f2a 0%, #090d17 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #0d111b 0%, #020309 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.
