# Pepsi gradient

Gradients derived from Pepsi'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, #0e0e96 0%, #e32934 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0e0e96] to-[#e32934]`
- Contrast (worst point): white 4.53:1 AA · black 1.52:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0e0e96-e32934?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.02 until the ink passes AA at the worst point (4.58:1).

- CSS: `linear-gradient(135deg in oklab, #1e2a50 0%, #a16661 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#1e2a50] to-[#a16661]`
- Contrast (worst point): white 4.58:1 AA · black 1.50:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1e2a50-a16661?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 10.41:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #1322a3 0%, #0c0089 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#1322a3] to-[#0c0089]`
- Contrast (worst point): white 11.76:1 AA · black 1.38:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1322a3-0c0089?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #182dad 0%, #0d0793 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #0f1499 0%, #0a0079 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #3053d3 0%, #0e0e96 50%, #020037 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#3053d3] via-[#0e0e96] to-[#020037]`
- Contrast (worst point): white 6.36:1 AA · black 1.06:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.3053d3-0e0e96-020037?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, #0e0e96 0%, #06374f 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0e0e96] to-[#06374f]`
- Contrast (worst point): white 12.54:1 AA · black 1.52:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0e0e96-06374f?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, #0e0e96 0%, #403005 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0e0e96] to-[#403005]`
- Contrast (worst point): white 12.73:1 AA · black 1.50:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0e0e96-403005?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, #0e0e96 0%, #62080a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0e0e96] to-[#62080a]`
- Contrast (worst point): white 13.15:1 AA · black 1.52:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0e0e96-62080a?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 4.53:1 AA, black 1.52:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #0e0e96 0%, #e32934 100%);
  /* hero — worst-case contrast: white 4.58:1 AA, black 1.50:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #1e2a50 0%, #a16661 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 11.76:1 AA, black 1.38:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #1322a3 0%, #0c0089 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #182dad 0%, #0d0793 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #0f1499 0%, #0a0079 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.
