# Gumroad gradient

Gradients derived from Gumroad'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 colors: https://brandsweets.com/colors/brands/gumroad-com · Brand page: https://brandsweets.com/b/gumroad-com

## Brand gradient

- CSS: `linear-gradient(135deg in oklab, #fc94ec 0%, #f1f333 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc94ec] to-[#f1f333]`
- Contrast (worst point): white 1.19:1 fail · black 10.59:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc94ec-f1f333?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). Passes AA for that ink at the worst point (11.13:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #d6b2cf 0%, #ebeeba 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#d6b2cf] to-[#ebeeba]`
- Contrast (worst point): white 1.20:1 fail · black 11.13:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.d6b2cf-ebeeba?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. Black ink passes AA on the surface and both states (worst 8.24:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #ffa1f9 0%, #ee87df 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ffa1f9] to-[#ee87df]`
- Contrast (worst point): white 1.79:1 fail · black 9.17:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.ffa1f9-ee87df?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #ffb2fd 0%, #f991e9 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #ff97ef 0%, #e47ed5 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffeeff 0%, #fc94ec 50%, #bf5cb1 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffeeff] via-[#fc94ec] to-[#bf5cb1]`
- Contrast (worst point): white 1.11:1 fail · black 5.38:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ffeeff-fc94ec-bf5cb1?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, #fc94ec 0%, #cdadfc 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc94ec] to-[#cdadfc]`
- Contrast (worst point): white 1.91:1 fail · black 10.55:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fc94ec-cdadfc?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, #fc94ec 0%, #2de27e 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fc94ec] to-[#2de27e]`
- Contrast (worst point): white 1.70:1 fail · black 10.08:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc94ec-2de27e?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, #fc94ec 0%, #e2bb26 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc94ec] to-[#e2bb26]`
- Contrast (worst point): white 1.84:1 fail · black 10.57:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc94ec-e2bb26?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.19:1, black 10.59:1 AA */
  --brand-gradient: linear-gradient(135deg in oklab, #fc94ec 0%, #f1f333 100%);
  /* hero — worst-case contrast: white 1.20:1, black 11.13:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #d6b2cf 0%, #ebeeba 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 1.79:1, black 9.17:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #ffa1f9 0%, #ee87df 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #ffb2fd 0%, #f991e9 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #ff97ef 0%, #e47ed5 100%);
  --brand-gradient-button-ink: #000000;
}
```

## 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.
