# Loom gradient

Gradients derived from Loom'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 0.000 < 0.15 between #1868db and #1868db — a 2-stop would read as a flat fill, so this is a tonal ramp of #1868db.

- CSS: `linear-gradient(135deg in oklch shorter hue, #60a3ff 0%, #1868db 50%, #002e9e 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#60a3ff] via-[#1868db] to-[#002e9e]`
- Contrast (worst point): white 2.57:1 fail · black 1.89:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.60a3ff-1868db-002e9e?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 (4.58:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #607797 0%, #2a4369 50%, #0d1634 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#607797] via-[#2a4369] to-[#0d1634]`
- Contrast (worst point): white 4.58:1 AA · black 1.18:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.607797-2a4369-0d1634?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 4.55:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #1868db 0%, #004fc0 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#1868db] to-[#004fc0]`
- Contrast (worst point): white 5.20:1 AA · black 2.88:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1868db-004fc0?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #2372e5 0%, #0058ca 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #60a3ff 0%, #1868db 50%, #002e9e 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#60a3ff] via-[#1868db] to-[#002e9e]`
- Contrast (worst point): white 2.57:1 fail · black 1.89:1 fail · banding high

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #1868db 0%, #1d799c 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#1868db] to-[#1d799c]`
- Contrast (worst point): white 4.91:1 AA · black 4.03:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.1868db-1d799c?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, #1868db 0%, #8f6719 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#1868db] to-[#8f6719]`
- Contrast (worst point): white 4.54:1 AA · black 4.04:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.1868db-8f6719?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, #1868db 0%, #c8213e 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#1868db] to-[#c8213e]`
- Contrast (worst point): white 5.17:1 AA · black 3.74:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.1868db-c8213e?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 2.57:1, black 1.89:1 */
  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #60a3ff 0%, #1868db 50%, #002e9e 100%);
  /* hero — worst-case contrast: white 4.58:1 AA, black 1.18:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #607797 0%, #2a4369 50%, #0d1634 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 5.20:1 AA, black 2.88:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #1868db 0%, #004fc0 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #2372e5 0%, #0058ca 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #095ed1 0%, #0045b6 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.
