# Clerk gradient

Gradients derived from Clerk'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, #007232 0%, #ef4444 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#007232] to-[#ef4444]`
- Contrast (worst point): white 3.76:1 AA-large · black 3.45:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.007232-ef4444?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.07 until the ink passes AA at the worst point (4.68:1).

- CSS: `linear-gradient(135deg in oklab, #37513b 0%, #9e6560 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#37513b] to-[#9e6560]`
- Contrast (worst point): white 4.68:1 AA · black 2.40:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.37513b-9e6560?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 4.53:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #1a7e3d 0%, #006627 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#1a7e3d] to-[#006627]`
- Contrast (worst point): white 5.13:1 AA · black 2.93:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1a7e3d-006627?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #278746 0%, #006f2f 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #087535 0%, #005d1e 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #4ea966 0%, #007232 50%, #003d06 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#4ea966] via-[#007232] to-[#003d06]`
- Contrast (worst point): white 2.92:1 fail · black 1.67:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.4ea966-007232-003d06?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, #007232 0%, #566700 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#007232] to-[#566700]`
- Contrast (worst point): white 6.05:1 AA · black 3.33:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.007232-566700?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, #007232 0%, #9c0097 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#007232] to-[#9c0097]`
- Contrast (worst point): white 6.05:1 AA · black 2.86:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.007232-9c0097?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, #007232 0%, #3224ff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#007232] to-[#3224ff]`
- Contrast (worst point): white 6.04:1 AA · black 2.83:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.007232-3224ff?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 3.76:1 AA-large, black 3.45:1 AA-large */
  --brand-gradient: linear-gradient(135deg in oklab, #007232 0%, #ef4444 100%);
  /* hero — worst-case contrast: white 4.68:1 AA, black 2.40:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #37513b 0%, #9e6560 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 5.13:1 AA, black 2.93:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #1a7e3d 0%, #006627 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #278746 0%, #006f2f 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #087535 0%, #005d1e 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.
