# Chime gradient

Gradients derived from Chime'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, #0d4029 0%, #1ec677 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0d4029] to-[#1ec677]`
- Contrast (worst point): white 2.23:1 fail · black 1.78:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0d4029-1ec677?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.18 until the ink passes AA at the worst point (4.69:1).

- CSS: `linear-gradient(135deg in oklab, #07120c 0%, #537d61 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#07120c] to-[#537d61]`
- Contrast (worst point): white 4.69:1 AA · black 1.10:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.07120c-537d61?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 8.85:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #1a4b33 0%, #00351f 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#1a4b33] to-[#00351f]`
- Contrast (worst point): white 10.01:1 AA · black 1.53:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1a4b33-00351f?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #23533b 0%, #093d27 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #10432b 0%, #002e18 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #437259 0%, #0d4029 50%, #001203 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#437259] via-[#0d4029] to-[#001203]`
- Contrast (worst point): white 5.54:1 AA · black 1.09:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.437259-0d4029-001203?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, #0d4029 0%, #293d0b 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0d4029] to-[#293d0b]`
- Contrast (worst point): white 11.72:1 AA · black 1.76:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0d4029-293d0b?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, #0d4029 0%, #5c0e4b 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0d4029] to-[#5c0e4b]`
- Contrast (worst point): white 11.35:1 AA · black 1.62:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0d4029-5c0e4b?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, #0d4029 0%, #2c158d 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0d4029] to-[#2c158d]`
- Contrast (worst point): white 11.72:1 AA · black 1.60:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0d4029-2c158d?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 2.23:1, black 1.78:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #0d4029 0%, #1ec677 100%);
  /* hero — worst-case contrast: white 4.69:1 AA, black 1.10:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #07120c 0%, #537d61 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 10.01:1 AA, black 1.53:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #1a4b33 0%, #00351f 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #23533b 0%, #093d27 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #10432b 0%, #002e18 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.
