# Volkswagen gradient

Gradients derived from Volkswagen'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 0.056 < 0.15 between #1b2236 and #293043 — a 2-stop would read as a flat fill, so this is a tonal ramp of #1b2236.

- CSS: `linear-gradient(135deg in oklch shorter hue, #485167 0%, #1b2236 50%, #00010a 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#485167] via-[#1b2236] to-[#00010a]`
- Contrast (worst point): white 7.93:1 AA · black 1.01:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.485167-1b2236-00010a?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 (7.94:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklch shorter hue, #4e5159 0%, #20232a 50%, #010204 100%)`

## 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 12.52:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #242c41 0%, #12182c 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#242c41] to-[#12182c]`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #485167 0%, #1b2236 50%, #00010a 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#485167] via-[#1b2236] to-[#00010a]`

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #1b2236 0%, #1d2429 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#1b2236] to-[#1d2429]`
- Contrast (worst point): white 15.66:1 AA · black 1.32:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.1b2236-1d2429?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 175° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #1b2236 0%, #25231c 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#1b2236] to-[#25231c]`
- Contrast (worst point): white 15.53:1 AA · black 1.33:1 fail · banding high

## Triadic

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

- CSS: `linear-gradient(135deg in oklab, #1b2236 0%, #2e1f1c 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#1b2236] to-[#2e1f1c]`
- Contrast (worst point): white 15.71:1 AA · black 1.32:1 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.
