# Prisma gradient

Gradients derived from Prisma'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

ΔE_OK 0.000 < 0.15 between #00bbcb and #00bbcb — a 2-stop would read as a flat fill, so this is a tonal ramp of #00bbcb.

- CSS: `linear-gradient(135deg in oklch shorter hue, #68f6ff 0%, #00bbcb 50%, #00818f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#68f6ff] via-[#00bbcb] to-[#00818f]`
- Contrast (worst point): white 1.29:1 fail · black 4.54:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.68f6ff-00bbcb-00818f?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). L shifted +0.01 until the ink passes AA at the worst point (4.63:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #c1eaec 0%, #89b1b6 50%, #5f7b7f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#c1eaec] via-[#89b1b6] to-[#5f7b7f]`
- Contrast (worst point): white 1.29:1 fail · black 4.63:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.c1eaec-89b1b6-5f7b7f?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. Black ink passes AA on the surface and both states (worst 7.05:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #28c8d8 0%, #00aebe 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#28c8d8] to-[#00aebe]`
- Contrast (worst point): white 2.03:1 fail · black 7.80:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.28c8d8-00aebe?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #39d2e2 0%, #00b8c8 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #10bece 0%, #00a5b5 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #68f6ff 0%, #00bbcb 50%, #00818f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#68f6ff] via-[#00bbcb] to-[#00818f]`
- Contrast (worst point): white 1.29:1 fail · black 4.54:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.68f6ff-00bbcb-00818f?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, #00bbcb 0%, #00c1a2 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#00bbcb] to-[#00c1a2]`
- Contrast (worst point): white 2.29:1 fail · black 8.94:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.00bbcb-00c1a2?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, #00bbcb 0%, #ff746b 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#00bbcb] to-[#ff746b]`
- Contrast (worst point): white 2.30:1 fail · black 7.94:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.00bbcb-ff746b?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, #00bbcb 0%, #f650ff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#00bbcb] to-[#f650ff]`
- Contrast (worst point): white 2.33:1 fail · black 7.50:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.00bbcb-f650ff?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.29:1, black 4.54:1 AA */
  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #68f6ff 0%, #00bbcb 50%, #00818f 100%);
  /* hero — worst-case contrast: white 1.29:1, black 4.63:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #c1eaec 0%, #89b1b6 50%, #5f7b7f 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 2.03:1, black 7.80:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #28c8d8 0%, #00aebe 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #39d2e2 0%, #00b8c8 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #10bece 0%, #00a5b5 100%);
  --brand-gradient-button-ink: #000000;
}
```

## 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.
