# Next.js gradient

Gradients derived from Next.js'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

ΔH 155° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #9162c0 0%, #449d5d 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#9162c0] to-[#449d5d]`
- Contrast (worst point): white 3.34:1 AA-large · black 4.71:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.9162c0-449d5d?a=135&in=oklch&hue=shorter

## 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 (4.65:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #6e6080 0%, #607b65 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#6e6080] to-[#607b65]`
- Contrast (worst point): white 4.65:1 AA · black 3.64:1 AA-large · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.6e6080-607b65?a=135&in=oklch&hue=shorter

## 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 −0.08 so white ink passes AA on the surface and both states (worst 4.64:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #8556b3 0%, #6e3e99 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#8556b3] to-[#6e3e99]`
- Contrast (worst point): white 5.28:1 AA · black 2.81:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.8556b3-6e3e99?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #8e5fbd 0%, #7647a3 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #7c4da9 0%, #653590 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #c999fc 0%, #9162c0 50%, #5d2c86 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#c999fc] via-[#9162c0] to-[#5d2c86]`
- Contrast (worst point): white 2.22:1 fail · black 2.17:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.c999fc-9162c0-5d2c86?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, #9162c0 0%, #6975c0 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#9162c0] to-[#6975c0]`
- Contrast (worst point): white 4.27:1 AA-large · black 4.69:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.9162c0-6975c0?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, #9162c0 0%, #718452 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#9162c0] to-[#718452]`
- Contrast (worst point): white 3.94:1 AA-large · black 4.71:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.9162c0-718452?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, #9162c0 0%, #987451 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#9162c0] to-[#987451]`
- Contrast (worst point): white 4.22:1 AA-large · black 4.70:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.9162c0-987451?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 3.34:1 AA-large, black 4.71:1 AA */
  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #9162c0 0%, #449d5d 100%);
  /* hero — worst-case contrast: white 4.65:1 AA, black 3.64:1 AA-large; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #6e6080 0%, #607b65 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 5.28:1 AA, black 2.81:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #8556b3 0%, #6e3e99 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #8e5fbd 0%, #7647a3 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #7c4da9 0%, #653590 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.
