# Sentry gradient

Gradients derived from Sentry'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/sentry-io · Brand page: https://brandsweets.com/b/sentry-io

## Brand gradient

- CSS: `linear-gradient(135deg in oklab, #f97583 0%, #6a5fc1 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#f97583] to-[#6a5fc1]`
- Contrast (worst point): white 2.66:1 fail · black 4.02:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.f97583-6a5fc1?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.15 until the ink passes AA at the worst point (4.53:1).

- CSS: `linear-gradient(135deg in oklab, #996a6c 0%, #403f60 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#996a6c] to-[#403f60]`
- Contrast (worst point): white 4.53:1 AA · black 2.10:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.996a6c-403f60?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. Black ink passes AA on the surface and both states (worst 6.03:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #ff828f 0%, #eb6877 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ff828f] to-[#eb6877]`
- Contrast (worst point): white 2.38:1 fail · black 6.78:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.ff828f-eb6877?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #ff919c 0%, #f57280 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #fd7886 0%, #e05f6e 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffcbce 0%, #f97583 50%, #ba3b4f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffcbce] via-[#f97583] to-[#ba3b4f]`
- Contrast (worst point): white 1.43:1 fail · black 3.83:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ffcbce-f97583-ba3b4f?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, #f97583 0%, #f966c1 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#f97583] to-[#f966c1]`
- Contrast (worst point): white 2.65:1 fail · black 7.69:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.f97583-f966c1?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, #f97583 0%, #2ebbbc 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#f97583] to-[#2ebbbc]`
- Contrast (worst point): white 2.34:1 fail · black 7.87:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.f97583-2ebbbc?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, #f97583 0%, #68bf29 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#f97583] to-[#68bf29]`
- Contrast (worst point): white 2.31:1 fail · black 7.90:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.f97583-68bf29?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 2.66:1, black 4.02:1 AA-large */
  --brand-gradient: linear-gradient(135deg in oklab, #f97583 0%, #6a5fc1 100%);
  /* hero — worst-case contrast: white 4.53:1 AA, black 2.10:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #996a6c 0%, #403f60 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 2.38:1, black 6.78:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #ff828f 0%, #eb6877 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #ff919c 0%, #f57280 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #fd7886 0%, #e05f6e 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.

## 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.
