# Apple gradient

Gradients derived from Apple'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, #221e1f 0%, #2997ff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#221e1f] to-[#2997ff]`
- Contrast (worst point): white 3.02:1 AA-large · black 1.27:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.221e1f-2997ff?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.11 until the ink passes AA at the worst point (4.65:1).

- CSS: `linear-gradient(135deg in oklab, #0a0909 0%, #58779a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0a0909] to-[#58779a]`
- Contrast (worst point): white 4.65:1 AA · black 1.06:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.0a0909-58779a?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 13.21:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #2c2829 0%, #191516 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#2c2829] to-[#191516]`
- Contrast (worst point): white 14.56:1 AA · black 1.16:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.2c2829-191516?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #332f30 0%, #201c1d 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #242021 0%, #120e0f 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #504c4d 0%, #221e1f 50%, #010101 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#504c4d] via-[#221e1f] to-[#010101]`
- Contrast (worst point): white 8.46:1 AA · black 1.01:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.504c4d-221e1f-010101?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, #221e1f 0%, #211e21 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#221e1f] to-[#211e21]`
- Contrast (worst point): white 16.48:1 AA · black 1.27:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.221e1f-211e21?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 164° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #221e1f 0%, #1e201f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#221e1f] to-[#1e201f]`
- Contrast (worst point): white 16.33:1 AA · black 1.27:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.221e1f-1e201f?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, #221e1f 0%, #1f1f1e 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#221e1f] to-[#1f1f1e]`
- Contrast (worst point): white 16.40:1 AA · black 1.27:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.221e1f-1f1f1e?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 3.02:1 AA-large, black 1.27:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #221e1f 0%, #2997ff 100%);
  /* hero — worst-case contrast: white 4.65:1 AA, black 1.06:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #0a0909 0%, #58779a 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 14.56:1 AA, black 1.16:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #2c2829 0%, #191516 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #332f30 0%, #201c1d 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #242021 0%, #120e0f 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.
