# ElevenLabs gradient

Gradients derived from ElevenLabs'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 #f41a2f and #f41a2f — a 2-stop would read as a flat fill, so this is a tonal ramp of #f41a2f.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff968e 0%, #f41a2f 50%, #a20009 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff968e] via-[#f41a2f] to-[#a20009]`
- Contrast (worst point): white 2.10:1 fail · black 2.54:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff968e-f41a2f-a20009?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.22 until the ink passes AA at the worst point (4.66:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #916b67 0%, #702f29 50%, #32060c 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#916b67] via-[#702f29] to-[#32060c]`
- Contrast (worst point): white 4.66:1 AA · black 1.17:1 fail · banding high · ink #ffffff

## 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 −0.08 so white ink gets as close as the ±0.1 bound allows to AA on the surface and both states (worst 4.36:1). Ink is below AA (4.36:1 at the worst point) — use it for large text only, or pick a darker/lighter primary for buttons.

- CSS: `linear-gradient(180deg in oklch shorter hue, #e50021 0%, #c0000f 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#e50021] to-[#c0000f]`
- Contrast (worst point): white 4.82:1 AA · black 3.25:1 AA-large · banding high · ink #ffffff

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff968e 0%, #f41a2f 50%, #a20009 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff968e] via-[#f41a2f] to-[#a20009]`
- Contrast (worst point): white 2.10:1 fail · black 2.54:1 fail · banding high

## Analogous

Partner hue from the analogous rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #f41a2f 0%, #e9198c 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#f41a2f] to-[#e9198c]`
- Contrast (worst point): white 4.15:1 AA-large · black 4.97:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.f41a2f-e9198c?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, #f41a2f 0%, #1696a2 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#f41a2f] to-[#1696a2]`
- Contrast (worst point): white 3.54:1 AA-large · black 5.01:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.f41a2f-1696a2?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, #f41a2f 0%, #16a031 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#f41a2f] to-[#16a031]`
- Contrast (worst point): white 3.42:1 AA-large · black 5.04:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.f41a2f-16a031?a=135

## CSS custom properties (brand.css)

```css

  /* button — worst-case contrast: white 4.82:1 AA, black 3.25:1 AA-large */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #e50021 0%, #c0000f 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #f0112c 0%, #d00013 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #da0015 0%, #b1000c 100%);
  --brand-gradient-button-ink: #ffffff;
  /* button ink: 4.4:1 — below AA */
}
```

## 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.
