# Wells Fargo gradient

Gradients derived from Wells Fargo'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, #d71e28 0%, #ffcd41 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#d71e28] to-[#ffcd41]`
- Contrast (worst point): white 1.49:1 fail · black 4.11:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.d71e28-ffcd41?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). L shifted +0.01 until the ink passes AA at the worst point (4.61:1).

- CSS: `linear-gradient(135deg in oklab, #a06761 0%, #e6d6ae 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#a06761] to-[#e6d6ae]`
- Contrast (worst point): white 1.44:1 fail · black 4.61:1 AA · banding medium · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.a06761-e6d6ae?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. L shifted −0.04 so white ink passes AA on the surface and both states (worst 4.51:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #d71e28 0%, #ba0008 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#d71e28] to-[#ba0008]`
- Contrast (worst point): white 5.12:1 AA · black 3.09:1 AA-large · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.d71e28-ba0008?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #e22d32 0%, #c50016 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #cc051e 0%, #ab0005 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff776e 0%, #d71e28 50%, #890001 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff776e] via-[#d71e28] to-[#890001]`
- Contrast (worst point): white 2.59:1 fail · black 2.06:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff776e-d71e28-890001?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, #d71e28 0%, #cd1d7a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#d71e28] to-[#cd1d7a]`
- Contrast (worst point): white 5.09:1 AA · black 4.05:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.d71e28-cd1d7a?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, #d71e28 0%, #1a848f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#d71e28] to-[#1a848f]`
- Contrast (worst point): white 4.29:1 AA-large · black 4.11:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.d71e28-1a848f?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, #d71e28 0%, #1a8d32 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#d71e28] to-[#1a8d32]`
- Contrast (worst point): white 4.27:1 AA-large · black 4.10:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.d71e28-1a8d32?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.49:1, black 4.11:1 AA-large */
  --brand-gradient: linear-gradient(135deg in oklab, #d71e28 0%, #ffcd41 100%);
  /* hero — worst-case contrast: white 1.44:1, black 4.61:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #a06761 0%, #e6d6ae 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 5.12:1 AA, black 3.09:1 AA-large */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #d71e28 0%, #ba0008 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #e22d32 0%, #c50016 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #cc051e 0%, #ab0005 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.
