# Deno gradient

Gradients derived from Deno'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 colors: https://brandsweets.com/colors/brands/deno-com · Brand page: https://brandsweets.com/b/deno-com
- Palette: primary #6639ba, secondary #70ffaf, accents #6639ba

## Brand gradient

- CSS: `linear-gradient(135deg in oklab, #6639ba 0%, #70ffaf 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#6639ba] to-[#70ffaf]`
- Contrast (worst point): white 1.26:1 fail · black 2.86:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.6639ba-70ffaf?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). L shifted +0.09 until the ink passes AA at the worst point (4.59:1).

- CSS: `linear-gradient(135deg in oklab, #797099 0%, #dbffe9 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#797099] to-[#dbffe9]`
- Contrast (worst point): white 1.08:1 fail · black 4.59:1 AA · banding medium · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.797099-dbffe9?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 5.40:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #7146c7 0%, #5b2bad 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#7146c7] to-[#5b2bad]`
- Contrast (worst point): white 6.17:1 AA · black 2.39:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.7146c7-5b2bad?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #7950d2 0%, #6336b7 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #693cbd 0%, #5420a3 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #9973f8 0%, #6639ba 50%, #38007d 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#9973f8] via-[#6639ba] to-[#38007d]`
- Contrast (worst point): white 3.41:1 AA-large · black 1.46:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.9973f8-6639ba-38007d?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, #6639ba 0%, #1f4fc6 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#6639ba] to-[#1f4fc6]`
- Contrast (worst point): white 7.00:1 AA · black 2.85:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.6639ba-1f4fc6?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, #6639ba 0%, #5c612a 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#6639ba] to-[#5c612a]`
- Contrast (worst point): white 6.55:1 AA · black 2.83:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.6639ba-5c612a?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, #6639ba 0%, #814d29 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#6639ba] to-[#814d29]`
- Contrast (worst point): white 6.90:1 AA · black 2.85:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.6639ba-814d29?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.26:1, black 2.86:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #6639ba 0%, #70ffaf 100%);
  /* hero — worst-case contrast: white 1.08:1, black 4.59:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #797099 0%, #dbffe9 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 6.17:1 AA, black 2.39:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #7146c7 0%, #5b2bad 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #7950d2 0%, #6336b7 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #693cbd 0%, #5420a3 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.
