# native Cybersecurity gradient

Gradients derived from native Cybersecurity'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 0.033 < 0.15 between #fc0404 and #ec0000 — a 2-stop would read as a flat fill, so this is a tonal ramp of #fc0404.

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff9b8b 0%, #fc0404 50%, #a70000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff9b8b] via-[#fc0404] to-[#a70000]`
- Contrast (worst point): white 2.04:1 fail · black 2.64:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff9b8b-fc0404-a70000?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.22 until the ink passes AA at the worst point (4.51:1).

- CSS: `linear-gradient(135deg in oklch shorter hue, #926e68 0%, #753026 50%, #36070c 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#926e68] via-[#753026] to-[#36070c]`
- Contrast (worst point): white 4.51:1 AA · black 1.19:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.926e68-753026-36070c?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 −0.08 so white ink gets as close as the ±0.1 bound allows to AA on the surface and both states (worst 4.21:1). Ink is below AA (4.21:1 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, #ed0000 0%, #c50000 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#ed0000] to-[#c50000]`
- Contrast (worst point): white 4.56:1 AA · black 3.37:1 AA-large · banding high · ink #ffffff

- Hover: `linear-gradient(180deg in oklch shorter hue, #f80000 0%, #d40000 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #ff9b8b 0%, #fc0404 50%, #a70000 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#ff9b8b] via-[#fc0404] to-[#a70000]`
- Contrast (worst point): white 2.04:1 fail · black 2.64:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.ff9b8b-fc0404-a70000?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, #fc0404 0%, #f20183 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc0404] to-[#f20183]`
- Contrast (worst point): white 4.06:1 AA-large · black 5.09:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.fc0404-f20183?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, #fc0404 0%, #0198aa 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#fc0404] to-[#0198aa]`
- Contrast (worst point): white 3.44:1 AA-large · black 5.13:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc0404-0198aa?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, #fc0404 0%, #01a246 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#fc0404] to-[#01a246]`
- Contrast (worst point): white 3.34:1 AA-large · black 5.15:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.fc0404-01a246?a=135

## CSS custom properties (brand.css)

```css

  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #ed0000 0%, #c50000 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #f80000 0%, #d40000 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #df0000 0%, #b60000 100%);
  --brand-gradient-button-ink: #ffffff;
  /* button ink: 4.2:1 — below AA */
}

## 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.
