# Philips gradient

Gradients derived from Philips'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, #15191e 0%, #0b5ed7 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#15191e] to-[#0b5ed7]`
- Contrast (worst point): white 5.84:1 AA · black 1.19:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.15191e-0b5ed7?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). Passes AA for that ink at the worst point (5.64:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #17191a 0%, #506890 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#17191a] to-[#506890]`
- Contrast (worst point): white 5.64:1 AA · black 1.19:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.17191a-506890?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 14.47:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #1e2228 0%, #0c1015 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#1e2228] to-[#0c1015]`
- Contrast (worst point): white 15.97:1 AA · black 1.10:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.1e2228-0c1015?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #252a2f 0%, #13171c 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #171b20 0%, #060a0e 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #41464c 0%, #15191e 50%, #000001 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#41464c] via-[#15191e] to-[#000001]`
- Contrast (worst point): white 9.52:1 AA · black 1.00:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.41464c-15191e-000001?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, #15191e 0%, #15191b 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#15191e] to-[#15191b]`
- Contrast (worst point): white 17.65:1 AA · black 1.19:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.15191e-15191b?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 173° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #15191e 0%, #1b1815 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#15191e] to-[#1b1815]`
- Contrast (worst point): white 17.61:1 AA · black 1.18:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.15191e-1b1815?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, #15191e 0%, #1f1617 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#15191e] to-[#1f1617]`
- Contrast (worst point): white 17.60:1 AA · black 1.18:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.15191e-1f1617?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 5.84:1 AA, black 1.19:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #15191e 0%, #0b5ed7 100%);
  /* hero — worst-case contrast: white 5.64:1 AA, black 1.19:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #17191a 0%, #506890 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 15.97:1 AA, black 1.10:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #1e2228 0%, #0c1015 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #252a2f 0%, #13171c 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #171b20 0%, #060a0e 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.
