# Rippling gradient

Gradients derived from Rippling'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, #ffa81d 0%, #9f1e7a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ffa81d] to-[#9f1e7a]`
- Contrast (worst point): white 1.93:1 fail · black 2.94:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ffa81d-9f1e7a?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.24 until the ink passes AA at the worst point (4.59:1).

- CSS: `linear-gradient(135deg in oklab, #8e704d 0%, #310825 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#8e704d] to-[#310825]`
- Contrast (worst point): white 4.59:1 AA · black 1.19:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.8e704d-310825?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 8.51:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #ffb63b 0%, #f19b00 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ffb63b] to-[#f19b00]`
- Contrast (worst point): white 1.75:1 fail · black 9.43:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.ffb63b-f19b00?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #ffc468 0%, #fca515 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #ffab24 0%, #e79200 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #fff3d5 0%, #ffa81d 50%, #be7200 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fff3d5] via-[#ffa81d] to-[#be7200]`
- Contrast (worst point): white 1.10:1 fail · black 5.60:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fff3d5-ffa81d-be7200?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, #ffa81d 0%, #ffa280 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ffa81d] to-[#ffa280]`
- Contrast (worst point): white 1.93:1 fail · black 10.71:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ffa81d-ffa280?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, #ffa81d 0%, #89c2ff 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffa81d] to-[#89c2ff]`
- Contrast (worst point): white 1.77:1 fail · black 10.87:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ffa81d-89c2ff?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, #ffa81d 0%, #00d9d2 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ffa81d] to-[#00d9d2]`
- Contrast (worst point): white 1.77:1 fail · black 10.84:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ffa81d-00d9d2?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.93:1, black 2.94:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #ffa81d 0%, #9f1e7a 100%);
  /* hero — worst-case contrast: white 4.59:1 AA, black 1.19:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #8e704d 0%, #310825 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 1.75:1, black 9.43:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #ffb63b 0%, #f19b00 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #ffc468 0%, #fca515 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #ffab24 0%, #e79200 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.
