# Fivetran blue gradient

Gradients derived from Fivetran blue'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 0.101 < 0.15 between #346cec and #2e54b6 — a 2-stop would read as a flat fill, so this is a tonal ramp of #346cec.

- CSS: `linear-gradient(135deg in oklch shorter hue, #7babff 0%, #346cec 50%, #0130ae 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#7babff] via-[#346cec] to-[#0130ae]`
- Contrast (worst point): white 2.31:1 fail · black 2.04:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.7babff-346cec-0130ae?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.18 until the ink passes AA at the worst point (4.59:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #657694 0%, #2b416b 50%, #090e35 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#657694] via-[#2b416b] to-[#090e35]`
- Contrast (worst point): white 4.59:1 AA · black 1.13:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.657694-2b416b-090e35?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 −0.07 so white ink passes AA on the surface and both states (worst 4.66:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #2c62e2 0%, #1548c6 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#2c62e2] to-[#1548c6]`
- Contrast (worst point): white 5.31:1 AA · black 2.77:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.2c62e2-1548c6?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #346cec 0%, #1d52d0 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #7babff 0%, #346cec 50%, #0130ae 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#7babff] via-[#346cec] to-[#0130ae]`
- Contrast (worst point): white 2.31:1 fail · black 2.04:1 fail · banding high

## Analogous

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

- CSS: `linear-gradient(135deg in oklab, #346cec 0%, #2b80a9 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#346cec] to-[#2b80a9]`
- Contrast (worst point): white 4.39:1 AA-large · black 4.49:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.346cec-2b80a9?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, #346cec 0%, #937126 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#346cec] to-[#937126]`
- Contrast (worst point): white 4.05:1 AA-large · black 4.49:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.346cec-937126?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, #346cec 0%, #d2313a 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#346cec] to-[#d2313a]`
- Contrast (worst point): white 4.63:1 AA · black 4.23:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.346cec-d2313a?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.
