# Linkedin gradient

Gradients derived from Linkedin'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 0.049 < 0.15 between #0073b1 and #0a66c2 — a 2-stop would read as a flat fill, so this is a tonal ramp of #0073b1.

- CSS: `linear-gradient(135deg in oklch shorter hue, #50abed 0%, #0073b1 50%, #003f72 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#50abed] via-[#0073b1] to-[#003f72]`
- Contrast (worst point): white 2.50:1 fail · black 1.95:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.50abed-0073b1-003f72?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.15 until the ink passes AA at the worst point (4.50:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #5e7a90 0%, #294358 50%, #0f1a26 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#5e7a90] via-[#294358] to-[#0f1a26]`
- Contrast (worst point): white 4.50:1 AA · black 1.20:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.5e7a90-294358-0f1a26?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 −0.04 so white ink passes AA on the surface and both states (worst 4.53:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #0073b1 0%, #005b97 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#0073b1] to-[#005b97]`
- Contrast (worst point): white 5.14:1 AA · black 2.94:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.0073b1-005b97?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #167cbb 0%, #0064a1 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #50abed 0%, #0073b1 50%, #003f72 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#50abed] via-[#0073b1] to-[#003f72]`
- Contrast (worst point): white 2.50:1 fail · black 1.95:1 fail · banding high

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #0073b1 0%, #007a8d 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0073b1] to-[#007a8d]`
- Contrast (worst point): white 5.02:1 AA · black 4.07:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0073b1-007a8d?a=135

## Complementary

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, #0073b1 0%, #9d5a00 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#0073b1] to-[#9d5a00]`
- Contrast (worst point): white 5.11:1 AA · black 3.75:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.0073b1-9d5a00?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, #0073b1 0%, #c60061 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0073b1] to-[#c60061]`
- Contrast (worst point): white 5.12:1 AA · black 3.56:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.0073b1-c60061?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 2.50:1, black 1.95:1 */
  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #50abed 0%, #0073b1 50%, #003f72 100%);
  /* hero — worst-case contrast: white 4.50:1 AA, black 1.20:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #5e7a90 0%, #294358 50%, #0f1a26 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 5.14:1 AA, black 2.94:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #0073b1 0%, #005b97 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #167cbb 0%, #0064a1 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #006aa7 0%, #00528e 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.
