# Abstract gradient

Gradients derived from Abstract'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, #141414 0%, #ff6900 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#141414] to-[#ff6900]`
- Contrast (worst point): white 2.89:1 fail · black 1.14:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.141414-ff6900?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.13 until the ink passes AA at the worst point (4.54:1).

- CSS: `linear-gradient(135deg in oklab, #010101 0%, #9d6a53 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#010101] to-[#9d6a53]`
- Contrast (worst point): white 4.54:1 AA · black 1.01:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.010101-9d6a53?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 15.52:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #1d1d1d 0%, #0b0b0b 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#1d1d1d] to-[#0b0b0b]`
- Contrast (worst point): white 16.86:1 AA · black 1.07:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1d1d1d-0b0b0b?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #242424 0%, #121212 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #161616 0%, #060606 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #404040 0%, #141414 50%, #000000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#404040] via-[#141414] to-[#000000]`
- Contrast (worst point): white 10.37:1 AA · black 1.00:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.404040-141414-000000?a=135&in=oklch&hue=shorter

## Analogous

Primary #141414 is achromatic — harmony rotates #ff6900 instead. Partner hue from the analogous rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #ff6900 0%, #ff5f78 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ff6900] to-[#ff5f78]`
- Contrast (worst point): white 2.88:1 fail · black 7.15:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff6900-ff5f78?a=135

## Complementary

Primary #141414 is achromatic — harmony rotates #ff6900 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, #ff6900 0%, #00afdb 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff6900] to-[#00afdb]`
- Contrast (worst point): white 2.41:1 fail · black 7.27:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ff6900-00afdb?a=135&in=oklch&hue=shorter

## Triadic

Primary #141414 is achromatic — harmony rotates #ff6900 instead. Partner hue from the triadic rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #ff6900 0%, #00ba86 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ff6900] to-[#00ba86]`
- Contrast (worst point): white 2.50:1 fail · black 7.27:1 AA · banding medium

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 2.89:1, black 1.14:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #141414 0%, #ff6900 100%);
  /* hero — worst-case contrast: white 4.54:1 AA, black 1.01:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #010101 0%, #9d6a53 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 16.86:1 AA, black 1.07:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #1d1d1d 0%, #0b0b0b 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #242424 0%, #121212 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #161616 0%, #060606 100%);
  --brand-gradient-button-ink: #ffffff;
}

## 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.
