# Linear gradient

Gradients derived from Linear'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 0.074 < 0.15 between #5e6ad2 and #7170ff — a 2-stop would read as a flat fill, so this is a tonal ramp of #5e6ad2.

- CSS: `linear-gradient(135deg in oklch shorter hue, #92a3ff 0%, #5e6ad2 50%, #313396 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#92a3ff] via-[#5e6ad2] to-[#313396]`
- Contrast (worst point): white 2.36:1 fail · black 2.04:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.92a3ff-5e6ad2-313396?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.18 until the ink passes AA at the worst point (4.66:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #6c7393 0%, #373e62 50%, #14142c 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#6c7393] via-[#373e62] to-[#14142c]`
- Contrast (worst point): white 4.66:1 AA · black 1.17:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.6c7393-373e62-14142c?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. L shifted −0.07 so white ink passes AA on the surface and both states (worst 4.70:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #5661c8 0%, #4249ad 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#5661c8] to-[#4249ad]`
- Contrast (worst point): white 5.33:1 AA · black 2.79:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.5661c8-4249ad?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #5e6ad2 0%, #4952b7 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #92a3ff 0%, #5e6ad2 50%, #313396 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#92a3ff] via-[#5e6ad2] to-[#313396]`
- Contrast (worst point): white 2.36:1 fail · black 2.04:1 fail · banding high

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #5e6ad2 0%, #427cab 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#5e6ad2] to-[#427cab]`
- Contrast (worst point): white 4.45:1 AA-large · black 4.45:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.5e6ad2-427cab?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, #5e6ad2 0%, #85763f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#5e6ad2] to-[#85763f]`
- Contrast (worst point): white 4.49:1 AA-large · black 4.32:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.5e6ad2-85763f?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, #5e6ad2 0%, #b6563e 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#5e6ad2] to-[#b6563e]`
- Contrast (worst point): white 4.65:1 AA · black 4.38:1 AA-large · banding high

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */

  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #92a3ff 0%, #5e6ad2 50%, #313396 100%);
  /* hero — worst-case contrast: white 4.66:1 AA, black 1.17:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #6c7393 0%, #373e62 50%, #14142c 100%);

  /* button — worst-case contrast: white 5.33:1 AA, black 2.79:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #5661c8 0%, #4249ad 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #5e6ad2 0%, #4952b7 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #4e58be 0%, #3a3fa3 100%);

## 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.
