# Mistral AI gradient

Gradients derived from Mistral AI'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

ΔH 168° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #54b4fc 0%, #ffaf01 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#54b4fc] to-[#ffaf01]`
- Contrast (worst point): white 1.84:1 fail · black 9.31:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.54b4fc-ffaf01?a=135&in=oklch&hue=shorter

## 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 (9.26:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklch shorter hue, #92b0c9 0%, #d8bc97 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#92b0c9] to-[#d8bc97]`
- Contrast (worst point): white 1.82:1 fail · black 9.26:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.92b0c9-d8bc97?a=135&in=oklch&hue=shorter

## 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 7.20:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #62c1ff 0%, #46a7ee 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#62c1ff] to-[#46a7ee]`
- Contrast (worst point): white 1.98:1 fail · black 8.02:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.62c1ff-46a7ee?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #76caff 0%, #51b1f9 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #57b7ff 0%, #3b9ee4 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #c3ebff 0%, #54b4fc 50%, #027bc0 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#c3ebff] via-[#54b4fc] to-[#027bc0]`
- Contrast (worst point): white 1.26:1 fail · black 4.60:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.c3ebff-54b4fc-027bc0?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, #54b4fc 0%, #1fbfdc 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#54b4fc] to-[#1fbfdc]`
- Contrast (worst point): white 2.19:1 fail · black 9.29:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.54b4fc-1fbfdc?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, #54b4fc 0%, #f1921b 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#54b4fc] to-[#f1921b]`
- Contrast (worst point): white 2.25:1 fail · black 8.54:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.54b4fc-f1921b?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, #54b4fc 0%, #fc7ca0 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#54b4fc] to-[#fc7ca0]`
- Contrast (worst point): white 2.25:1 fail · black 8.49:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.54b4fc-fc7ca0?a=135

## CSS custom properties (brand.css)

```css
:root {

  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #54b4fc 0%, #ffaf01 100%);
  /* hero — worst-case contrast: white 1.82:1, black 9.26:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #92b0c9 0%, #d8bc97 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 1.98:1, black 8.02:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #62c1ff 0%, #46a7ee 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #76caff 0%, #51b1f9 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #57b7ff 0%, #3b9ee4 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.
