# Neon gradient

Gradients derived from Neon'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 colors: https://brandsweets.com/colors/brands/neon-tech · Brand page: https://brandsweets.com/b/neon-tech

## Brand gradient

- CSS: `linear-gradient(135deg in oklab, #34d59a 0%, #285d49 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#34d59a] to-[#285d49]`
- Contrast (worst point): white 1.89:1 fail · black 2.75:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.34d59a-285d49?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.23 until the ink passes AA at the worst point (4.67:1).

- CSS: `linear-gradient(135deg in oklab, #537d68 0%, #0e1b15 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#537d68] to-[#0e1b15]`
- Contrast (worst point): white 4.67:1 AA · black 1.19:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.537d68-0e1b15?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. Black ink passes AA on the surface and both states (worst 8.70:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #47e2a6 0%, #1ac88e 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#47e2a6] to-[#1ac88e]`
- Contrast (worst point): white 1.65:1 fail · black 9.70:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.47e2a6-1ac88e?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #54ecb0 0%, #2ed297 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #39d89d 0%, #00be85 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #b4ffdf 0%, #34d59a 50%, #009b64 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#b4ffdf] via-[#34d59a] to-[#009b64]`
- Contrast (worst point): white 1.15:1 fail · black 5.87:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.b4ffdf-34d59a-009b64?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, #34d59a 0%, #80d12e 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#34d59a] to-[#80d12e]`
- Contrast (worst point): white 1.88:1 fail · black 11.03:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.34d59a-80d12e?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, #34d59a 0%, #fa8bd1 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#34d59a] to-[#fa8bd1]`
- Contrast (worst point): white 1.83:1 fail · black 9.63:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.34d59a-fa8bd1?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, #34d59a 0%, #adaefa 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#34d59a] to-[#adaefa]`
- Contrast (worst point): white 1.88:1 fail · black 10.18:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.34d59a-adaefa?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.89:1, black 2.75:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #34d59a 0%, #285d49 100%);
  /* hero — worst-case contrast: white 4.67:1 AA, black 1.19:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #537d68 0%, #0e1b15 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 1.65:1, black 9.70:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #47e2a6 0%, #1ac88e 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #54ecb0 0%, #2ed297 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #39d89d 0%, #00be85 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.
