# dbt Labs gradient

Gradients derived from dbt Labs'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 145° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #fc6304 0%, #1e2939 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fc6304] to-[#1e2939]`
- Contrast (worst point): white 3.03:1 AA-large · black 1.43:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc6304-1e2939?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.12 until the ink passes AA at the worst point (4.59:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #9d6953 0%, #0d1116 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#9d6953] to-[#0d1116]`
- Contrast (worst point): white 4.59:1 AA · black 1.11:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.9d6953-0d1116?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 3.40:1). Ink is below AA (3.40:1 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, #e64f00 0%, #c53900 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#e64f00] to-[#c53900]`
- Contrast (worst point): white 3.83:1 AA-large · black 3.96:1 AA-large · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.e64f00-c53900?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #f15900 0%, #d33f00 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffbe9f 0%, #fc6304 50%, #b23200 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffbe9f] via-[#fc6304] to-[#b23200]`
- Contrast (worst point): white 1.60:1 fail · black 3.35:1 AA-large · banding high

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #fc6304 0%, #ff5576 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc6304] to-[#ff5576]`
- Contrast (worst point): white 3.03:1 AA-large · black 6.81:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fc6304-ff5576?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, #fc6304 0%, #05abd3 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fc6304] to-[#05abd3]`

- Maker: https://brandsweets.com/gradients/new/v1.fc6304-05abd3?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, #fc6304 0%, #06b67f 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc6304] to-[#06b67f]`
- Contrast (worst point): white 2.61:1 fail · black 6.93:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc6304-06b67f?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.

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.
