# Sweetgreen gradient

Gradients derived from Sweetgreen'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, #0e150e 0%, #d8e5d6 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0e150e] to-[#d8e5d6]`
- Contrast (worst point): white 1.30:1 fail · black 1.13:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0e150e-d8e5d6?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.36 until the ink passes AA at the worst point (4.62:1).

- CSS: `linear-gradient(135deg in oklab, #010101 0%, #727671 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#010101] to-[#727671]`
- Contrast (worst point): white 4.62:1 AA · black 1.01:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.010101-727671?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 15.69:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #171e17 0%, #060c06 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#171e17] to-[#060c06]`
- Contrast (worst point): white 17.01:1 AA · black 1.06:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.171e17-060c06?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #1e251e 0%, #0c130c 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #101710 0%, #030603 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #394139 0%, #0e150e 50%, #000100 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#394139] via-[#0e150e] to-[#000100]`
- Contrast (worst point): white 10.56:1 AA · black 1.00:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.394139-0e150e-000100?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, #0e150e 0%, #13140d 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0e150e] to-[#13140d]`
- Contrast (worst point): white 18.46:1 AA · black 1.13:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0e150e-13140d?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 178° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #0e150e 0%, #190f19 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0e150e] to-[#190f19]`
- Contrast (worst point): white 18.51:1 AA · black 1.12:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0e150e-190f19?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, #0e150e 0%, #0b1223 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0e150e] to-[#0b1223]`
- Contrast (worst point): white 18.51:1 AA · black 1.12:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0e150e-0b1223?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.30:1, black 1.13:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #0e150e 0%, #d8e5d6 100%);
  /* hero — worst-case contrast: white 4.62:1 AA, black 1.01:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #010101 0%, #727671 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 17.01:1 AA, black 1.06:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #171e17 0%, #060c06 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #1e251e 0%, #0c130c 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #101710 0%, #030603 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.
