# Puma gradient

Gradients derived from Puma'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, #191919 0%, #a78b55 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#191919] to-[#a78b55]`
- Contrast (worst point): white 3.25:1 AA-large · black 1.19:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.191919-a78b55?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.09 until the ink passes AA at the worst point (4.67:1).

- CSS: `linear-gradient(135deg in oklab, #070707 0%, #7d7361 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#070707] to-[#7d7361]`
- Contrast (worst point): white 4.67:1 AA · black 1.04:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.070707-7d7361?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 14.35:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #222222 0%, #101010 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#222222] to-[#101010]`
- Contrast (worst point): white 15.91:1 AA · black 1.10:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.222222-101010?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #2a2a2a 0%, #171717 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #1b1b1b 0%, #0a0a0a 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #464646 0%, #191919 50%, #000000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#464646] via-[#191919] to-[#000000]`

## Analogous

Primary #191919 is achromatic — harmony rotates #a78b55 instead. Partner hue from the analogous rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #a78b55 0%, #be7e54 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#a78b55] to-[#be7e54]`
- Contrast (worst point): white 3.24:1 AA-large · black 6.28:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.a78b55-be7e54?a=135

## Complementary

Primary #191919 is achromatic — harmony rotates #a78b55 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, #a78b55 0%, #6b8ed3 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#a78b55] to-[#6b8ed3]`

## Triadic

Primary #191919 is achromatic — harmony rotates #a78b55 instead. Partner hue from the triadic rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #a78b55 0%, #5c9ba1 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#a78b55] to-[#5c9ba1]`
- Contrast (worst point): white 3.14:1 AA-large · black 6.45:1 AA · 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.
