# Allbirds gradient

Gradients derived from Allbirds'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 0.098 < 0.15 between #241c24 and #090c43 — a 2-stop would read as a flat fill, so this is a tonal ramp of #241c24.

- CSS: `linear-gradient(135deg in oklch shorter hue, #534953 0%, #241c24 50%, #020002 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#534953] via-[#241c24] to-[#020002]`
- Contrast (worst point): white 8.59:1 AA · black 1.00:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.534953-241c24-020002?a=135&in=oklch&hue=shorter

## 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 (8.56:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklch shorter hue, #4f4b4f 0%, #211e21 50%, #010001 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#4f4b4f] via-[#211e21] to-[#010001]`
- Contrast (worst point): white 8.56:1 AA · black 1.00:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.4f4b4f-211e21-010001?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. White ink passes AA on the surface and both states (worst 13.31:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #2e262e 0%, #1b131b 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#2e262e] to-[#1b131b]`
- Contrast (worst point): white 14.66:1 AA · black 1.16:1 fail · banding high · ink #ffffff

- Hover: `linear-gradient(180deg in oklch shorter hue, #352d35 0%, #221a22 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #534953 0%, #241c24 50%, #020002 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#534953] via-[#241c24] to-[#020002]`
- Contrast (worst point): white 8.59:1 AA · black 1.00:1 fail · banding high

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #241c24 0%, #201d29 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#241c24] to-[#201d29]`
- Contrast (worst point): white 16.50:1 AA · black 1.26:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.241c24-201d29?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 176° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #241c24 0%, #1b211c 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#241c24] to-[#1b211c]`
- Contrast (worst point): white 16.35:1 AA · black 1.26:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.241c24-1b211c?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, #241c24 0%, #211f1b 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#241c24] to-[#211f1b]`
- Contrast (worst point): white 16.38:1 AA · black 1.26:1 fail · banding high

## 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.
