# Unity gradient

Gradients derived from Unity'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, #0892ff 0%, #0000ff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0892ff] to-[#0000ff]`
- Contrast (worst point): white 3.20:1 AA-large · black 2.44:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0892ff-0000ff?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.09 until the ink passes AA at the worst point (4.54:1).

- CSS: `linear-gradient(135deg in oklab, #57799d 0%, #1b3877 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#57799d] to-[#1b3877]`
- Contrast (worst point): white 4.54:1 AA · black 1.88:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.57799d-1b3877?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. L shifted −0.10 so white ink gets as close as the ±0.1 bound allows to AA on the surface and both states (worst 3.60:1). Ink is below AA (3.60:1 at the worst point) — use it for large text only, or pick a darker/lighter primary for buttons.

- CSS: `linear-gradient(180deg in oklch shorter hue, #007fea 0%, #0065ce 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#007fea] to-[#0065ce]`
- Contrast (worst point): white 4.02:1 AA-large · black 3.75:1 AA-large · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.007fea-0065ce?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #0088f4 0%, #006fd9 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #0075e0 0%, #005dbf 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #94ceff 0%, #0892ff 50%, #005abb 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#94ceff] via-[#0892ff] to-[#005abb]`
- Contrast (worst point): white 1.68:1 fail · black 3.18:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.94ceff-0892ff-005abb?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, #0892ff 0%, #00a0c4 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0892ff] to-[#00a0c4]`
- Contrast (worst point): white 3.07:1 AA-large · black 6.54:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0892ff-00a0c4?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, #0892ff 0%, #c57f00 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0892ff] to-[#c57f00]`
- Contrast (worst point): white 3.20:1 AA-large · black 6.04:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0892ff-c57f00?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, #0892ff 0%, #ff2e6a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0892ff] to-[#ff2e6a]`
- Contrast (worst point): white 3.18:1 AA-large · black 5.83:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0892ff-ff2e6a?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 3.20:1 AA-large, black 2.44:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #0892ff 0%, #0000ff 100%);
  /* hero — worst-case contrast: white 4.54:1 AA, black 1.88:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #57799d 0%, #1b3877 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 4.02:1 AA-large, black 3.75:1 AA-large */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #007fea 0%, #0065ce 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #0088f4 0%, #006fd9 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #0075e0 0%, #005dbf 100%);
  --brand-gradient-button-ink: #ffffff;
  /* button ink: 3.6:1 — below AA */
}
```

## 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.
