# Gopro gradient

Gradients derived from Gopro'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, #0059c2 0%, #0097d6 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0059c2] to-[#0097d6]`
- Contrast (worst point): white 3.28:1 AA-large · black 3.21:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0059c2-0097d6?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.08 until the ink passes AA at the worst point (4.62:1).

- CSS: `linear-gradient(135deg in oklab, #31486b 0%, #58798f 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#31486b] to-[#58798f]`
- Contrast (worst point): white 4.62:1 AA · black 2.27:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.31486b-58798f?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 4.83:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #1566d0 0%, #004db5 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#1566d0] to-[#004db5]`
- Contrast (worst point): white 5.46:1 AA · black 2.73:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1566d0-004db5?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #216fda 0%, #0056bf 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #055cc5 0%, #0043ab 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #4692ff 0%, #0059c2 50%, #001f86 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#4692ff] via-[#0059c2] to-[#001f86]`
- Contrast (worst point): white 3.08:1 AA-large · black 1.54:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.4692ff-0059c2-001f86?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, #0059c2 0%, #006989 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0059c2] to-[#006989]`
- Contrast (worst point): white 6.19:1 AA · black 3.20:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0059c2-006989?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 179° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #0059c2 0%, #7e5700 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0059c2] to-[#7e5700]`
- Contrast (worst point): white 5.75:1 AA · black 3.21:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0059c2-7e5700?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, #0059c2 0%, #b30032 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0059c2] to-[#b30032]`
- Contrast (worst point): white 6.50:1 AA · black 2.95:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0059c2-b30032?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 3.28:1 AA-large, black 3.21:1 AA-large */
  --brand-gradient: linear-gradient(135deg in oklab, #0059c2 0%, #0097d6 100%);
  /* hero — worst-case contrast: white 4.62:1 AA, black 2.27:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #31486b 0%, #58798f 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 5.46:1 AA, black 2.73:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #1566d0 0%, #004db5 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #216fda 0%, #0056bf 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #055cc5 0%, #0043ab 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.
