# Confluent gradient

Gradients derived from Confluent'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, #143464 0%, #0079ff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#143464] to-[#0079ff]`
- Contrast (worst point): white 4.05:1 AA-large · black 1.71:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.143464-0079ff?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.04 until the ink passes AA at the worst point (4.65:1).

- CSS: `linear-gradient(135deg in oklab, #232b3a 0%, #5776a2 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#232b3a] to-[#5776a2]`
- Contrast (worst point): white 4.65:1 AA · black 1.48:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.232b3a-5776a2?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 9.29:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #1f3f70 0%, #092958 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#1f3f70] to-[#092958]`
- Contrast (worst point): white 10.48:1 AA · black 1.47:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1f3f70-092958?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #264779 0%, #113161 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #173767 0%, #022150 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #44679b 0%, #143464 50%, #000431 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#44679b] via-[#143464] to-[#000431]`
- Contrast (worst point): white 5.74:1 AA · black 1.06:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.44679b-143464-000431?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, #143464 0%, #173a49 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#143464] to-[#173a49]`
- Contrast (worst point): white 12.03:1 AA · black 1.70:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.143464-173a49?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, #143464 0%, #443214 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#143464] to-[#443214]`
- Contrast (worst point): white 12.21:1 AA · black 1.65:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.143464-443214?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, #143464 0%, #5e1a21 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#143464] to-[#5e1a21]`
- Contrast (worst point): white 12.24:1 AA · black 1.65:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.143464-5e1a21?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 4.05:1 AA-large, black 1.71:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #143464 0%, #0079ff 100%);
  /* hero — worst-case contrast: white 4.65:1 AA, black 1.48:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #232b3a 0%, #5776a2 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 10.48:1 AA, black 1.47:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #1f3f70 0%, #092958 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #264779 0%, #113161 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #173767 0%, #022150 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.
