# Cisco gradient

Gradients derived from Cisco'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

- CSS: `linear-gradient(135deg in oklab, #07182d 0%, #0a60ff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#07182d] to-[#0a60ff]`
- Contrast (worst point): white 5.08:1 AA · black 1.18:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.07182d-0a60ff?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). Passes AA for that ink at the worst point (4.83:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #13181f 0%, #5672a5 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#13181f] to-[#5672a5]`
- Contrast (worst point): white 4.83:1 AA · black 1.18:1 fail · banding medium · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.13181f-5672a5?a=135

## 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. White ink passes AA on the surface and both states (worst 14.73:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #102237 0%, #010f23 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#102237] to-[#010f23]`
- Contrast (worst point): white 16.08:1 AA · black 1.09:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.102237-010f23?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #17293f 0%, #05162a 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #091a30 0%, #00081b 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #33465e 0%, #07182d 50%, #000007 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#33465e] via-[#07182d] to-[#000007]`
- Contrast (worst point): white 9.64:1 AA · black 1.00:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.33465e-07182d-000007?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, #07182d 0%, #081a21 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#07182d] to-[#081a21]`
- Contrast (worst point): white 17.73:1 AA · black 1.18:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.07182d-081a21?a=135

## Complementary

Partner hue from the complementary rule at the source colour's lightness. ΔH 178° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

- CSS: `linear-gradient(135deg in oklch shorter hue, #07182d 0%, #201607 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#07182d] to-[#201607]`
- Contrast (worst point): white 17.45:1 AA · black 1.18:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.07182d-201607?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, #07182d 0%, #2d090f 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#07182d] to-[#2d090f]`
- Contrast (worst point): white 17.80:1 AA · black 1.16:1 fail · banding high
- Maker: https://brandsweets.com/gradients/new/v1.07182d-2d090f?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 5.08:1 AA, black 1.18:1 */
  --brand-gradient: linear-gradient(135deg in oklab, #07182d 0%, #0a60ff 100%);
  /* hero — worst-case contrast: white 4.83:1 AA, black 1.18:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #13181f 0%, #5672a5 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 16.08:1 AA, black 1.09:1 */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #102237 0%, #010f23 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #17293f 0%, #05162a 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #091a30 0%, #00081b 100%);
  --brand-gradient-button-ink: #ffffff;
}
```

## 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.

## Connect an agent

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.
