# Instacart gradient

Gradients derived from Instacart'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, #043b2b 0%, #108910 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#043b2b] to-[#108910]`
- Contrast (worst point): white 4.56:1 AA · black 1.67:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.043b2b-108910?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 (4.74:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #27352f 0%, #5c7b59 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#27352f] to-[#5c7b59]`
- Contrast (worst point): white 4.74:1 AA · black 1.64:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.27352f-5c7b59?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 9.52:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #134635 0%, #003121 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#134635] to-[#003121]`
- Contrast (worst point): white 10.74:1 AA · black 1.46:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.134635-003121?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #1c4e3d 0%, #013829 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #083e2d 0%, #00291a 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #3c6d5b 0%, #043b2b 50%, #000e05 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#3c6d5b] via-[#043b2b] to-[#000e05]`
- Contrast (worst point): white 5.95:1 AA · black 1.06:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.3c6d5b-043b2b-000e05?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, #043b2b 0%, #163b03 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#043b2b] to-[#163b03]`
- Contrast (worst point): white 12.61:1 AA · black 1.66:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.043b2b-163b03?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, #043b2b 0%, #5a053d 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#043b2b] to-[#5a053d]`
- Contrast (worst point): white 12.21:1 AA · black 1.52:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.043b2b-5a053d?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, #043b2b 0%, #340781 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#043b2b] to-[#340781]`
- Contrast (worst point): white 12.55:1 AA · black 1.49:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.043b2b-340781?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 4.56:1 AA, black 1.67:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #043b2b 0%, #108910 100%);
  /* hero — worst-case contrast: white 4.74:1 AA, black 1.64:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #27352f 0%, #5c7b59 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 10.74:1 AA, black 1.46:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #134635 0%, #003121 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #1c4e3d 0%, #013829 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #083e2d 0%, #00291a 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.
