# Cohere gradient

Gradients derived from Cohere'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, #00754e 0%, #14142a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#00754e] to-[#14142a]`
- Contrast (worst point): white 5.75:1 AA · black 1.16:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.00754e-14142a?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 (5.99:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #4f695b 0%, #16161e 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#4f695b] to-[#16161e]`
- Contrast (worst point): white 5.99:1 AA · black 1.17:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.4f695b-16161e?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 −0.02 so white ink passes AA on the surface and both states (worst 4.65:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #107b54 0%, #00633e 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#107b54] to-[#00633e]`
- Contrast (worst point): white 5.27:1 AA · black 2.85:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.107b54-00633e?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #20845c 0%, #006c46 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #00724b 0%, #005b36 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #4fac82 0%, #00754e 50%, #004022 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#4fac82] via-[#00754e] to-[#004022]`
- Contrast (worst point): white 2.78:1 fail · black 1.76:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.4fac82-00754e-004022?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, #00754e 0%, #447100 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#00754e] to-[#447100]`
- Contrast (worst point): white 5.72:1 AA · black 3.59:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.00754e-447100?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, #00754e 0%, #aa0084 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#00754e] to-[#aa0084]`
- Contrast (worst point): white 5.72:1 AA · black 3.04:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.00754e-aa0084?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, #00754e 0%, #5b0cff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#00754e] to-[#5b0cff]`
- Contrast (worst point): white 5.72:1 AA · black 2.94:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.00754e-5b0cff?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 5.75:1 AA, black 1.16:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #00754e 0%, #14142a 100%);
  /* hero — worst-case contrast: white 5.99:1 AA, black 1.17:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #4f695b 0%, #16161e 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 5.27:1 AA, black 2.85:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #107b54 0%, #00633e 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #20845c 0%, #006c46 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #00724b 0%, #005b36 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.
