# FedEx gradient

Gradients derived from FedEx'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, #4d148c 0%, #ff6600 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#4d148c] to-[#ff6600]`
- Contrast (worst point): white 2.94:1 fail · black 1.79:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.4d148c-ff6600?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.13 until the ink passes AA at the worst point (4.63:1).

- CSS: `linear-gradient(135deg in oklab, #231633 0%, #9d6852 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#231633] to-[#9d6852]`
- Contrast (worst point): white 4.63:1 AA · black 1.23:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.231633-9d6852?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 8.69:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #572499 0%, #43007f 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#572499] to-[#43007f]`
- Contrast (worst point): white 9.92:1 AA · black 1.54:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.572499-43007f?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #602ea3 0%, #4a0f89 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #50188f 0%, #3b0076 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #7e51c7 0%, #4d148c 50%, #1c003f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#7e51c7] via-[#4d148c] to-[#1c003f]`
- Contrast (worst point): white 5.40:1 AA · black 1.12:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.7e51c7-4d148c-1c003f?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, #4d148c 0%, #171aae 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#4d148c] to-[#171aae]`
- Contrast (worst point): white 11.63:1 AA · black 1.79:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.4d148c-171aae?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, #4d148c 0%, #3b430c 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#4d148c] to-[#3b430c]`
- Contrast (worst point): white 10.50:1 AA · black 1.79:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.4d148c-3b430c?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, #4d148c 0%, #5c320b 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#4d148c] to-[#5c320b]`
- Contrast (worst point): white 10.94:1 AA · black 1.79:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.4d148c-5c320b?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 2.94:1, black 1.79:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #4d148c 0%, #ff6600 100%);
  /* hero — worst-case contrast: white 4.63:1 AA, black 1.23:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #231633 0%, #9d6852 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 9.92:1 AA, black 1.54:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #572499 0%, #43007f 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #602ea3 0%, #4a0f89 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #50188f 0%, #3b0076 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.
