# Wise gradient

Gradients derived from Wise'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, #f4243b 0%, #9fe870 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#f4243b] to-[#9fe870]`
- Contrast (worst point): white 1.47:1 fail · black 5.16:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.f4243b-9fe870?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 (5.60:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #b3736f 0%, #c0d9b2 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#b3736f] to-[#c0d9b2]`
- Contrast (worst point): white 1.52:1 fail · black 5.60:1 AA · banding medium · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.b3736f-c0d9b2?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. L shifted −0.08 so white ink gets as close as the ±0.1 bound allows to AA on the surface and both states (worst 4.24:1). Ink is below AA (4.24:1 at the worst point) — use it for large text only, or pick a darker/lighter primary for buttons.

- CSS: `linear-gradient(180deg in oklch shorter hue, #e5002e 0%, #c3001b 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#e5002e] to-[#c3001b]`
- Contrast (worst point): white 4.80:1 AA · black 3.34:1 AA-large · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.e5002e-c3001b?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #f01e38 0%, #d2001f 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #da0025 0%, #b40017 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff9994 0%, #f4243b 50%, #a50014 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff9994] via-[#f4243b] to-[#a50014]`
- Contrast (worst point): white 2.05:1 fail · black 2.61:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff9994-f4243b-a50014?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, #f4243b 0%, #e92392 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#f4243b] to-[#e92392]`
- Contrast (worst point): white 4.05:1 AA-large · black 5.11:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.f4243b-e92392?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, #f4243b 0%, #2098a1 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#f4243b] to-[#2098a1]`
- Contrast (worst point): white 3.37:1 AA-large · black 5.16:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.f4243b-2098a1?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, #f4243b 0%, #20a225 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#f4243b] to-[#20a225]`
- Contrast (worst point): white 3.34:1 AA-large · black 5.16:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.f4243b-20a225?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.47:1, black 5.16:1 AA */
  --brand-gradient: linear-gradient(135deg in oklab, #f4243b 0%, #9fe870 100%);
  /* hero — worst-case contrast: white 1.52:1, black 5.60:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #b3736f 0%, #c0d9b2 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 4.80:1 AA, black 3.34:1 AA-large */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #e5002e 0%, #c3001b 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #f01e38 0%, #d2001f 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #da0025 0%, #b40017 100%);
  --brand-gradient-button-ink: #ffffff;
  /* button ink: 4.2:1 — below AA */
}
```

## 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.

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.
