# Todoist gradient

Gradients derived from Todoist'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 0.003 < 0.15 between #e44434 and #e34432 — a 2-stop would read as a flat fill, so this is a tonal ramp of #e44434.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff9886 0%, #e44434 50%, #a40000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff9886] via-[#e44434] to-[#a40000]`
- Contrast (worst point): white 2.08:1 fail · black 2.58:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff9886-e44434-a40000?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.22 until the ink passes AA at the worst point (4.63:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #916c65 0%, #69332b 50%, #34060b 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#916c65] via-[#69332b] to-[#34060b]`
- Contrast (worst point): white 4.63:1 AA · black 1.18:1 fail · banding high · ink #ffffff

## 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 −0.10 so white ink passes AA on the surface and both states (worst 4.60:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #ce2d1f 0%, #b20000 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ce2d1f] to-[#b20000]`
- Contrast (worst point): white 5.22:1 AA · black 2.89:1 fail · banding high · ink #ffffff

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff9886 0%, #e44434 50%, #a40000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff9886] via-[#e44434] to-[#a40000]`

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #e44434 0%, #dd4081 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#e44434] to-[#dd4081]`
- Contrast (worst point): white 4.05:1 AA-large · black 5.11:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.e44434-dd4081?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, #e44434 0%, #3b93a1 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#e44434] to-[#3b93a1]`
- Contrast (worst point): white 3.56:1 AA-large · black 5.15:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.e44434-3b93a1?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, #e44434 0%, #3c9b56 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#e44434] to-[#3c9b56]`
- Contrast (worst point): white 3.48:1 AA-large · black 5.17:1 AA · banding high

## CSS custom properties (brand.css)

```css

  /* button — worst-case contrast: white 5.22:1 AA, black 2.89:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #ce2d1f 0%, #b20000 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.
