# Airbnb gradient

Gradients derived from Airbnb'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 0.048 < 0.15 between #ff5a5f and #ff385c — a 2-stop would read as a flat fill, so this is a tonal ramp of #ff5a5f.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffbcb8 0%, #ff5a5f 50%, #be0c2a 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffbcb8] via-[#ff5a5f] to-[#be0c2a]`
- Contrast (worst point): white 1.60:1 fail · black 3.27:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ffbcb8-ff5a5f-be0c2a?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). L shifted +0.06 until the ink passes AA at the worst point (4.58:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #f3dbd9 0%, #d59c99 50%, #9c6865 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#f3dbd9] via-[#d59c99] to-[#9c6865]`
- Contrast (worst point): white 1.32:1 fail · black 4.58:1 AA · banding high · ink #000000

## 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 −0.10 so white ink gets as close as the ±0.1 bound allows to AA on the surface and both states (worst 3.43:1). Ink is below AA (3.43:1 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, #e9454d 0%, #cc2536 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#e9454d] to-[#cc2536]`
- Contrast (worst point): white 3.87:1 AA-large · black 3.88:1 AA-large · banding high · ink #ffffff

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffbcb8 0%, #ff5a5f 50%, #be0c2a 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffbcb8] via-[#ff5a5f] to-[#be0c2a]`
- Contrast (worst point): white 1.60:1 fail · black 3.27:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ffbcb8-ff5a5f-be0c2a?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, #ff5a5f 0%, #ff46a9 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ff5a5f] to-[#ff46a9]`
- Contrast (worst point): white 3.05:1 AA-large · black 6.69:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff5a5f-ff46a9?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, #ff5a5f 0%, #00b0ba 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff5a5f] to-[#00b0ba]`
- Contrast (worst point): white 2.60:1 fail · black 6.88:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ff5a5f-00b0ba?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, #ff5a5f 0%, #10bc09 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ff5a5f] to-[#10bc09]`
- Contrast (worst point): white 2.55:1 fail · black 6.88:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ff5a5f-10bc09?a=135

## CSS custom properties (brand.css)

```css

  --brand-gradient-button-ink: #ffffff;
  /* button ink: 3.4:1 — 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.
