# Ahrefs gradient

Gradients derived from Ahrefs'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 0.123 < 0.15 between #fc8c04 and #fac000 — a 2-stop would read as a flat fill, so this is a tonal ramp of #fc8c04.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffdcb7 0%, #fc8c04 50%, #b75900 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffdcb7] via-[#fc8c04] to-[#b75900]`
- Contrast (worst point): white 1.30:1 fail · black 4.44:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ffdcb7-fc8c04-b75900?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 (4.61:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ede1d4 0%, #cba486 50%, #906f5b 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ede1d4] via-[#cba486] to-[#906f5b]`
- Contrast (worst point): white 1.29:1 fail · black 4.61:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.ede1d4-cba486-906f5b?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 6.89:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #ff9926 0%, #ee7f00 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ff9926] to-[#ee7f00]`
- Contrast (worst point): white 2.13:1 fail · black 7.67:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.ff9926-ee7f00?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #ffa852 0%, #f88900 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #ff8f10 0%, #e47600 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffdcb7 0%, #fc8c04 50%, #b75900 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffdcb7] via-[#fc8c04] to-[#b75900]`
- Contrast (worst point): white 1.30:1 fail · black 4.44:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ffdcb7-fc8c04-b75900?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, #fc8c04 0%, #ff8373 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc8c04] to-[#ff8373]`
- Contrast (worst point): white 2.36:1 fail · black 8.74:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fc8c04-ff8373?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, #fc8c04 0%, #3db8ff 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fc8c04] to-[#3db8ff]`
- Contrast (worst point): white 2.21:1 fail · black 8.34:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc8c04-3db8ff?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, #fc8c04 0%, #05c8ae 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc8c04] to-[#05c8ae]`
- Contrast (worst point): white 2.12:1 fail · black 8.88:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc8c04-05c8ae?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.
