# Stanley gradient

Gradients derived from Stanley'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, #000000 0%, #22725f 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#000000] to-[#22725f]`
- Contrast (worst point): white 5.77:1 AA · black 1.00:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.000000-22725f?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 (5.91:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #000000 0%, #526961 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#000000] to-[#526961]`
- Contrast (worst point): white 5.91:1 AA · black 1.00:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.000000-526961?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 19.91:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #090909 0%, #010101 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#090909] to-[#010101]`
- Contrast (worst point): white 19.91:1 AA · black 1.01:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.090909-010101?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #090909 0%, #010101 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #090909 0%, #010101 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #3d3d3d 0%, #000000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#3d3d3d] to-[#000000]`
- Contrast (worst point): white 10.86:1 AA · black 1.00:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.3d3d3d-000000?a=135&in=oklch&hue=shorter

## Analogous

Primary #000000 is achromatic — harmony rotates #22725f instead. Partner hue from the analogous rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #22725f 0%, #227625 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#22725f] to-[#227625]`
- Contrast (worst point): white 5.67:1 AA · black 3.63:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.22725f-227625?a=135

## Complementary

Primary #000000 is achromatic — harmony rotates #22725f instead. 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, #22725f 0%, #a9246a 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#22725f] to-[#a9246a]`
- Contrast (worst point): white 5.74:1 AA · black 3.14:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.22725f-a9246a?a=135&in=oklch&hue=shorter

## Triadic

Primary #000000 is achromatic — harmony rotates #22725f instead. Partner hue from the triadic rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #22725f 0%, #712cd9 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#22725f] to-[#712cd9]`
- Contrast (worst point): white 5.75:1 AA · black 3.06:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.22725f-712cd9?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 5.77:1 AA, black 1.00:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #000000 0%, #22725f 100%);
  /* hero — worst-case contrast: white 5.91:1 AA, black 1.00:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #000000 0%, #526961 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 19.91:1 AA, black 1.01:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #090909 0%, #010101 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #090909 0%, #010101 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #090909 0%, #010101 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.

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.
