# Zillow gradient

Gradients derived from Zillow'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 0.012 < 0.15 between #0443dc and #0444d4 — a 2-stop would read as a flat fill, so this is a tonal ramp of #0443dc.

- CSS: `linear-gradient(135deg in oklch shorter hue, #4785ff 0%, #0443dc 50%, #000097 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#4785ff] via-[#0443dc] to-[#000097]`
- Contrast (worst point): white 3.46:1 AA-large · black 1.45:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.4785ff-0443dc-000097?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.07 until the ink passes AA at the worst point (4.50:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #6177a1 0%, #2d4574 50%, #0e183f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#6177a1] via-[#2d4574] to-[#0e183f]`
- Contrast (worst point): white 4.50:1 AA · black 1.22:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.6177a1-2d4574-0e183f?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 5.39:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #1251ea 0%, #0034ce 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#1251ea] to-[#0034ce]`
- Contrast (worst point): white 6.19:1 AA · black 2.38:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1251ea-0034ce?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #1c5cf5 0%, #013fd8 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #4785ff 0%, #0443dc 50%, #000097 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#4785ff] via-[#0443dc] to-[#000097]`
- Contrast (worst point): white 3.46:1 AA-large · black 1.45:1 fail · banding high

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #0443dc 0%, #0a6287 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0443dc] to-[#0a6287]`
- Contrast (worst point): white 6.72:1 AA · black 2.83:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0443dc-0a6287?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 179° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #0443dc 0%, #735508 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0443dc] to-[#735508]`
- Contrast (worst point): white 6.19:1 AA · black 2.84:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0443dc-735508?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, #0443dc 0%, #a90c22 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0443dc] to-[#a90c22]`
- Contrast (worst point): white 7.19:1 AA · black 2.75:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0443dc-a90c22?a=135

## CSS custom properties (brand.css)

```css

  /* button — worst-case contrast: white 6.19:1 AA, black 2.38:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #1251ea 0%, #0034ce 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #1c5cf5 0%, #013fd8 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #0747e0 0%, #0027c4 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.
