# Postman gradient

Gradients derived from Postman'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 0.077 < 0.15 between #fc6c34 and #e05320 — a 2-stop would read as a flat fill, so this is a tonal ramp of #fc6c34.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffc5ac 0%, #fc6c34 50%, #bc2e00 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffc5ac] via-[#fc6c34] to-[#bc2e00]`
- Contrast (worst point): white 1.52:1 fail · black 3.53:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ffc5ac-fc6c34-bc2e00?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). L shifted +0.05 until the ink passes AA at the worst point (4.64:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #f3ded5 0%, #d2a08f 50%, #9a6b5f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#f3ded5] via-[#d2a08f] to-[#9a6b5f]`
- Contrast (worst point): white 1.29:1 fail · black 4.64:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.f3ded5-d2a08f-9a6b5f?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 5.58:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #ff7943 0%, #ee5f24 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ff7943] to-[#ee5f24]`
- Contrast (worst point): white 2.60:1 fail · black 6.30:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.ff7943-ee5f24?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #ff8c5e 0%, #f86930 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ffc5ac 0%, #fc6c34 50%, #bc2e00 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ffc5ac] via-[#fc6c34] to-[#bc2e00]`
- Contrast (worst point): white 1.52:1 fail · black 3.53:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ffc5ac-fc6c34-bc2e00?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, #fc6c34 0%, #fc6283 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc6c34] to-[#fc6283]`
- Contrast (worst point): white 2.86:1 fail · black 7.20:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fc6c34-fc6283?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, #fc6c34 0%, #1cb0d4 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fc6c34] to-[#1cb0d4]`
- Contrast (worst point): white 2.55:1 fail · black 7.24:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc6c34-1cb0d4?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, #fc6c34 0%, #1cbb7d 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc6c34] to-[#1cbb7d]`
- Contrast (worst point): white 2.48:1 fail · black 7.33:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc6c34-1cbb7d?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.
