# Svelte gradient

Gradients derived from Svelte'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

ΔE_OK 0.000 < 0.15 between #d43008 and #d43008 — a 2-stop would read as a flat fill, so this is a tonal ramp of #d43008.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff7c5e 0%, #d43008 50%, #8b0000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff7c5e] via-[#d43008] to-[#8b0000]`
- Contrast (worst point): white 2.53:1 fail · black 2.10:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff7c5e-d43008-8b0000?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.17 until the ink passes AA at the worst point (4.67:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #97695e 0%, #693428 50%, #30080f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#97695e] via-[#693428] to-[#30080f]`
- Contrast (worst point): white 4.67:1 AA · black 1.17:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.97695e-693428-30080f?a=135&in=oklch&hue=shorter

## 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. L shifted −0.05 so white ink passes AA on the surface and both states (worst 4.58:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #d02c01 0%, #b40000 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#d02c01] to-[#b40000]`
- Contrast (worst point): white 5.20:1 AA · black 2.94:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.d02c01-b40000?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #db3815 0%, #be1100 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff7c5e 0%, #d43008 50%, #8b0000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff7c5e] via-[#d43008] to-[#8b0000]`
- Contrast (worst point): white 2.53:1 fail · black 2.10:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff7c5e-d43008-8b0000?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, #d43008 0%, #d60d69 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#d43008] to-[#d60d69]`
- Contrast (worst point): white 4.96:1 AA · black 4.12:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.d43008-d60d69?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, #d43008 0%, #0b8599 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#d43008] to-[#0b8599]`
- Contrast (worst point): white 4.33:1 AA-large · black 4.20:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.d43008-0b8599?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, #d43008 0%, #0b8e4c 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#d43008] to-[#0b8e4c]`
- Contrast (worst point): white 4.19:1 AA-large · black 4.21:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.d43008-0b8e4c?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 2.53:1, black 2.10:1 */
  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #ff7c5e 0%, #d43008 50%, #8b0000 100%);
  /* hero — worst-case contrast: white 4.67:1 AA, black 1.17:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #97695e 0%, #693428 50%, #30080f 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 5.20:1 AA, black 2.94:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #d02c01 0%, #b40000 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #db3815 0%, #be1100 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #c61d00 0%, #a70000 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.

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.
