# Robinhood gradient

Gradients derived from Robinhood'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

ΔH 142° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ccfc04 0%, #0000ee 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ccfc04] to-[#0000ee]`
- Contrast (worst point): white 1.20:1 fail · black 2.23:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ccfc04-0000ee?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). L shifted +0.13 until the ink passes AA at the worst point (4.54:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #f4ffcd 0%, #5974af 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#f4ffcd] to-[#5974af]`
- Contrast (worst point): white 1.05:1 fail · black 4.54:1 AA · banding medium · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.f4ffcd-5974af?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. Black ink passes AA on the surface and both states (worst 14.09:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #ddff6b 0%, #bfee00 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ddff6b] to-[#bfee00]`
- Contrast (worst point): white 1.13:1 fail · black 15.45:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.ddff6b-bfee00?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #e9ffa7 0%, #c4f400 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #cfff15 0%, #b6e400 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ccfc04 0%, #668300 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ccfc04] to-[#668300]`
- Contrast (worst point): white 1.20:1 fail · black 4.81:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ccfc04-668300?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, #ccfc04 0%, #ffe591 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ccfc04] to-[#ffe591]`
- Contrast (worst point): white 1.20:1 fail · black 16.82:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ccfc04-ffe591?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, #ccfc04 0%, #ebdfff 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ccfc04] to-[#ebdfff]`
- Contrast (worst point): white 1.20:1 fail · black 15.65:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ccfc04-ebdfff?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, #ccfc04 0%, #d0eaff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#ccfc04] to-[#d0eaff]`
- Contrast (worst point): white 1.20:1 fail · black 16.87:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.ccfc04-d0eaff?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.20:1, black 2.23:1 */
  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #ccfc04 0%, #0000ee 100%);
  /* hero — worst-case contrast: white 1.05:1, black 4.54:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #f4ffcd 0%, #5974af 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 1.13:1, black 15.45:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #ddff6b 0%, #bfee00 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #e9ffa7 0%, #c4f400 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #cfff15 0%, #b6e400 100%);
  --brand-gradient-button-ink: #000000;
}
```

## 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.
