# Together AI gradient

Gradients derived from Together AI'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

ΔH 164° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #fc4c02 0%, #c8f6f9 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fc4c02] to-[#c8f6f9]`
- Contrast (worst point): white 1.17:1 fail · black 6.17:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc4c02-c8f6f9?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 (6.59:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklch shorter hue, #bd8271 0%, #e0eff0 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#bd8271] to-[#e0eff0]`
- Contrast (worst point): white 1.18:1 fail · black 6.59:1 AA · banding medium · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.bd8271-e0eff0?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. L shifted −0.10 so white ink gets as close as the ±0.1 bound allows to AA on the surface and both states (worst 3.82:1). Ink is below AA (3.82:1 at the worst point) — use it for large text only, or pick a darker/lighter primary for buttons.

- CSS: `linear-gradient(180deg in oklch shorter hue, #e63400 0%, #c31c00 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#e63400] to-[#c31c00]`
- Contrast (worst point): white 4.33:1 AA-large · black 3.49:1 AA-large · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.e63400-c31c00?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #f14100 0%, #d22100 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #db2600 0%, #b51700 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffb196 0%, #fc4c02 50%, #b01500 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffb196] via-[#fc4c02] to-[#b01500]`
- Contrast (worst point): white 1.75:1 fail · black 2.95:1 fail · banding high

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #fc4c02 0%, #ff357a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc4c02] to-[#ff357a]`
- Contrast (worst point): white 3.40:1 AA-large · black 6.04:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fc4c02-ff357a?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, #fc4c02 0%, #03a4c1 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fc4c02] to-[#03a4c1]`

- Maker: https://brandsweets.com/gradients/new/v1.fc4c02-03a4c1?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, #fc4c02 0%, #03ae6a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc4c02] to-[#03ae6a]`
- Contrast (worst point): white 2.88:1 fail · black 6.17:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc4c02-03ae6a?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.
