# Fenty Beauty gradient

Gradients derived from Fenty Beauty'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, #2d2929 0%, #bd0100 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#2d2929] to-[#bd0100]`
- Contrast (worst point): white 6.63:1 AA · black 1.46:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.2d2929-bd0100?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 (6.14:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #2b2a2a 0%, #88544c 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#2b2a2a] to-[#88544c]`
- Contrast (worst point): white 6.14:1 AA · black 1.47:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.2b2a2a-88544c?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 11.05:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #373333 0%, #231f1f 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#373333] to-[#231f1f]`

## 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.
