# Chevrolet gradient

Gradients derived from Chevrolet'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

- CSS: `linear-gradient(135deg in oklab, #262626 0%, #0077d9 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#262626] to-[#0077d9]`
- Contrast (worst point): white 4.52:1 AA · black 1.39:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.262626-0077d9?a=135

## 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 (4.50:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #262626 0%, #5d799a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#262626] to-[#5d799a]`
- Contrast (worst point): white 4.50:1 AA · black 1.39:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.262626-5d799a?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. White ink passes AA on the surface and both states (worst 11.90:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #303030 0%, #1d1d1d 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#303030] to-[#1d1d1d]`
- Contrast (worst point): white 13.20:1 AA · black 1.25:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.303030-1d1d1d?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #373737 0%, #242424 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #282828 0%, #161616 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #555555 0%, #262626 50%, #020202 100%)`

- CSS: `linear-gradient(135deg in oklab, #0077d9 0%, #0084a4 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0077d9] to-[#0084a4]`
- Contrast (worst point): white 4.32:1 AA-large · black 4.62:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0077d9-0084a4?a=135

## Complementary

Primary #262626 is achromatic — harmony rotates #0077d9 instead. 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, #0077d9 0%, #a26a00 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0077d9] to-[#a26a00]`

## Triadic

Primary #262626 is achromatic — harmony rotates #0077d9 instead. Partner hue from the triadic rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #0077d9 0%, #db0050 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0077d9] to-[#db0050]`

## 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.
