# Binance gradient

Gradients derived from Binance'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 0.072 < 0.15 between #fcd535 and #f0b90b — a 2-stop would read as a flat fill, so this is a tonal ramp of #fcd535.

- CSS: `linear-gradient(135deg in oklch shorter hue, #fff8ad 0%, #fcd535 50%, #c09b00 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fff8ad] via-[#fcd535] to-[#c09b00]`
- Contrast (worst point): white 1.09:1 fail · black 7.93:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fff8ad-fcd535-c09b00?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 (7.98:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklch shorter hue, #f8f6dd 0%, #e4d8ad 50%, #ab9f7c 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#f8f6dd] via-[#e4d8ad] to-[#ab9f7c]`
- Contrast (worst point): white 1.09:1 fail · black 7.98:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.f8f6dd-e4d8ad-ab9f7c?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 11.70:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #ffe248 0%, #efc81c 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ffe248] to-[#efc81c]`
- Contrast (worst point): white 1.29:1 fail · black 12.95:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.ffe248-efc81c?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #ffee7b 0%, #f9d230 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #fff8ad 0%, #fcd535 50%, #c09b00 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fff8ad] via-[#fcd535] to-[#c09b00]`
- Contrast (worst point): white 1.09:1 fail · black 7.93:1 AA · banding high

## Analogous

Partner hue from the analogous rule at the source colour's lightness.

- CSS: `linear-gradient(135deg in oklab, #fcd535 0%, #fccea3 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fcd535] to-[#fccea3]`
- Contrast (worst point): white 1.42:1 fail · black 14.47:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fcd535-fccea3?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, #fcd535 0%, #cdd6fc 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fcd535] to-[#cdd6fc]`
- Contrast (worst point): white 1.43:1 fail · black 13.57:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fcd535-cdd6fc?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, #fcd535 0%, #8fe8fc 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fcd535] to-[#8fe8fc]`
- Contrast (worst point): white 1.38:1 fail · black 14.68:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fcd535-8fe8fc?a=135

## 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.
