# Ikea gradient

Gradients derived from Ikea'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

ΔE_OK 0.005 < 0.15 between #fcdc04 and #ffdb00 — a 2-stop would read as a flat fill, so this is a tonal ramp of #fcdc04.

- CSS: `linear-gradient(135deg in oklch shorter hue, #fffa97 0%, #fcdc04 50%, #bea200 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fffa97] via-[#fcdc04] to-[#bea200]`
- Contrast (worst point): white 1.08:1 fail · black 8.36:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fffa97-fcdc04-bea200?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). Passes AA for that ink at the worst point (8.37:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklch shorter hue, #f8f7d6 0%, #e7ddac 50%, #aca47f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#f8f7d6] via-[#e7ddac] to-[#aca47f]`
- Contrast (worst point): white 1.09:1 fail · black 8.37:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.f8f7d6-e7ddac-aca47f?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 12.32:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #ffe92e 0%, #efcf00 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ffe92e] to-[#efcf00]`
- Contrast (worst point): white 1.24:1 fail · black 13.60:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.ffe92e-efcf00?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #fff473 0%, #f9d900 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #ffdf15 0%, #e5c500 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #fffa97 0%, #fcdc04 50%, #bea200 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fffa97] via-[#fcdc04] to-[#bea200]`
- Contrast (worst point): white 1.08:1 fail · black 8.36:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fffa97-fcdc04-bea200?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, #fcdc04 0%, #ffd3a4 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fcdc04] to-[#ffd3a4]`
- Contrast (worst point): white 1.36:1 fail · black 15.08:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fcdc04-ffd3a4?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 179° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #fcdc04 0%, #d4d9ff 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fcdc04] to-[#d4d9ff]`
- Contrast (worst point): white 1.36:1 fail · black 14.14:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fcdc04-d4d9ff?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, #fcdc04 0%, #a0e9ff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fcdc04] to-[#a0e9ff]`
- Contrast (worst point): white 1.34:1 fail · black 15.32:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fcdc04-a0e9ff?a=135

## CSS custom properties (brand.css)

  /* button — worst-case contrast: white 1.24:1, black 13.60:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #ffe92e 0%, #efcf00 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #fff473 0%, #f9d900 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.
