# Monzo gradient

Gradients derived from Monzo'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

- CSS: `linear-gradient(135deg in oklab, #14233c 0%, #ff4f40 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#14233c] to-[#ff4f40]`
- Contrast (worst point): white 3.26:1 AA-large · black 1.33:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.14233c-ff4f40?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.10 until the ink passes AA at the worst point (4.53:1).

- CSS: `linear-gradient(135deg in oklab, #0a1018 0%, #a2675e 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#0a1018] to-[#a2675e]`
- Contrast (worst point): white 4.53:1 AA · black 1.10:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.0a1018-a2675e?a=135

## 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 12.35:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #1d2d47 0%, #0b1931 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#1d2d47] to-[#0b1931]`
- Contrast (worst point): white 13.83:1 AA · black 1.20:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1d2d47-0b1931?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #25354f 0%, #122139 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #16253f 0%, #05122a 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #41526e 0%, #14233c 50%, #00000f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#41526e] via-[#14233c] to-[#00000f]`
- Contrast (worst point): white 7.90:1 AA · black 1.01:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.41526e-14233c-00000f?a=135&in=oklch&hue=shorter

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #14233c 0%, #16262d 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#14233c] to-[#16262d]`
- Contrast (worst point): white 15.51:1 AA · black 1.33:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.14233c-16262d?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, #14233c 0%, #2a2215 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#14233c] to-[#2a2215]`
- Contrast (worst point): white 15.64:1 AA · black 1.31:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.14233c-2a2215?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, #14233c 0%, #381819 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#14233c] to-[#381819]`
- Contrast (worst point): white 15.66:1 AA · black 1.31:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.14233c-381819?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 3.26:1 AA-large, black 1.33:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #14233c 0%, #ff4f40 100%);
  /* hero — worst-case contrast: white 4.53:1 AA, black 1.10:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #0a1018 0%, #a2675e 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 13.83:1 AA, black 1.20:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #1d2d47 0%, #0b1931 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #25354f 0%, #122139 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #16253f 0%, #05122a 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.

## Connect an agent

Point any MCP client at the BrandSweets gradients endpoint for the same engine and corpus:

- Endpoint: https://mcp.brandsweets.com/gradients/mcp
- Tools: `make_gradient` (2–5 colours → CSS with the interpolation space, Tailwind v4, SVG, PNG URL, DTCG token + the contrast/banding/gamut report), `brand_gradients` (brand slug or palette → brand gradient, hero, button, variants).
- Resource: `gradients://corpus` — the whole bundled corpus as JSON.
