# Mailchimp gradient

Gradients derived from Mailchimp'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, #241c15 0%, #ffe01b 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#241c15] to-[#ffe01b]`
- Contrast (worst point): white 1.32:1 fail · black 1.25:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.241c15-ffe01b?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 (4.65:1).

- CSS: `linear-gradient(135deg in oklab, #010101 0%, #7e7544 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#010101] to-[#7e7544]`
- Contrast (worst point): white 4.65:1 AA · black 1.01:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.010101-7e7544?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 13.52:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #2e261e 0%, #1b130c 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#2e261e] to-[#1b130c]`
- Contrast (worst point): white 14.87:1 AA · black 1.15:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.2e261e-1b130c?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #352d25 0%, #221a13 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #261e17 0%, #140c06 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #534941 0%, #241c15 50%, #010000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#534941] via-[#241c15] to-[#010000]`
- Contrast (worst point): white 8.76:1 AA · black 1.00:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.534941-241c15-010000?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, #241c15 0%, #2a1915 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#241c15] to-[#2a1915]`
- Contrast (worst point): white 16.73:1 AA · black 1.24:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.241c15-2a1915?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 179° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #241c15 0%, #161f26 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#241c15] to-[#161f26]`
- Contrast (worst point): white 16.56:1 AA · black 1.25:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.241c15-161f26?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, #241c15 0%, #16201e 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#241c15] to-[#16201e]`
- Contrast (worst point): white 16.63:1 AA · black 1.25:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.241c15-16201e?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.32:1, black 1.25:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #241c15 0%, #ffe01b 100%);
  /* hero — worst-case contrast: white 4.65:1 AA, black 1.01:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #010101 0%, #7e7544 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 14.87:1 AA, black 1.15:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #2e261e 0%, #1b130c 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #352d25 0%, #221a13 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #261e17 0%, #140c06 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.
