# Datadog gradient

Gradients derived from Datadog'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, #632ca6 0%, #bf0000 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#632ca6] to-[#bf0000]`
- Contrast (worst point): white 6.53:1 AA · black 2.43:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.632ca6-bf0000?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). Passes AA for that ink at the worst point (6.11:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #574a71 0%, #89544c 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#574a71] to-[#89544c]`
- Contrast (worst point): white 6.11:1 AA · black 2.62:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.574a71-89544c?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 6.32:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #6e39b3 0%, #581d99 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#6e39b3] to-[#581d99]`
- Contrast (worst point): white 7.24:1 AA · black 2.05:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.6e39b3-581d99?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #7743bd 0%, #6029a3 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #662fa9 0%, #50108f 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #9766e2 0%, #632ca6 50%, #320063 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#9766e2] via-[#632ca6] to-[#320063]`
- Contrast (worst point): white 3.95:1 AA-large · black 1.32:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.9766e2-632ca6-320063?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, #632ca6 0%, #2835cb 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#632ca6] to-[#2835cb]`
- Contrast (worst point): white 8.50:1 AA · black 2.43:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.632ca6-2835cb?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, #632ca6 0%, #4d5820 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#632ca6] to-[#4d5820]`
- Contrast (worst point): white 7.15:1 AA · black 2.44:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.632ca6-4d5820?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, #632ca6 0%, #72461f 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#632ca6] to-[#72461f]`
- Contrast (worst point): white 8.02:1 AA · black 2.43:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.632ca6-72461f?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 6.53:1 AA, black 2.43:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #632ca6 0%, #bf0000 100%);
  /* hero — worst-case contrast: white 6.11:1 AA, black 2.62:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #574a71 0%, #89544c 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 7.24:1 AA, black 2.05:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #6e39b3 0%, #581d99 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #7743bd 0%, #6029a3 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #662fa9 0%, #50108f 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.
