# CircleCI gradient

Gradients derived from CircleCI'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, #005700 0%, #00db75 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#005700] to-[#00db75]`
- Contrast (worst point): white 1.84:1 fail · black 2.36:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.005700-00db75?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.23 until the ink passes AA at the worst point (4.57:1).

- CSS: `linear-gradient(135deg in oklab, #041404 0%, #51805d 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#041404] to-[#51805d]`
- Contrast (worst point): white 4.57:1 AA · black 1.11:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.041404-51805d?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 6.60:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #146312 0%, #004c00 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#146312] to-[#004c00]`
- Contrast (worst point): white 7.44:1 AA · black 2.03:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.146312-004c00?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #206b1c 0%, #005400 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #055a04 0%, #004300 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #438c3f 0%, #005700 50%, #002300 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#438c3f] via-[#005700] to-[#002300]`
- Contrast (worst point): white 4.15:1 AA-large · black 1.24:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.438c3f-005700-002300?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, #005700 0%, #484b00 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#005700] to-[#484b00]`
- Contrast (worst point): white 8.84:1 AA · black 2.27:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.005700-484b00?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, #005700 0%, #71007f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#005700] to-[#71007f]`
- Contrast (worst point): white 8.53:1 AA · black 2.00:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.005700-71007f?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, #005700 0%, #0037aa 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#005700] to-[#0037aa]`
- Contrast (worst point): white 8.78:1 AA · black 2.12:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.005700-0037aa?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.84:1, black 2.36:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #005700 0%, #00db75 100%);
  /* hero — worst-case contrast: white 4.57:1 AA, black 1.11:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #041404 0%, #51805d 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 7.44:1 AA, black 2.03:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #146312 0%, #004c00 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #206b1c 0%, #005400 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #055a04 0%, #004300 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.
