# Twilio gradient

Gradients derived from Twilio'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 0.000 < 0.15 between #3acefa and #3acefa — a 2-stop would read as a flat fill, so this is a tonal ramp of #3acefa.

- CSS: `linear-gradient(135deg in oklch shorter hue, #d6feff 0%, #3acefa 50%, #0094be 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#d6feff] via-[#3acefa] to-[#0094be]`
- Contrast (worst point): white 1.08:1 fail · black 5.98:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.d6feff-3acefa-0094be?a=135&in=oklch&hue=shorter

## Hero background

Chroma ×0.35 so it can carry text; ink black (inkFor at the midpoint). Passes AA for that ink at the worst point (5.86:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklch shorter hue, #eaf8f8 0%, #9cc3d2 50%, #6c8c9a 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#eaf8f8] via-[#9cc3d2] to-[#6c8c9a]`
- Contrast (worst point): white 1.09:1 fail · black 5.86:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.eaf8f8-9cc3d2-6c8c9a?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 8.88:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #4cdbff 0%, #24c1ec 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#4cdbff] to-[#24c1ec]`
- Contrast (worst point): white 1.63:1 fail · black 9.91:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.4cdbff-24c1ec?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #69e4ff 0%, #35cbf7 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #3fd1fd 0%, #05b7e2 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #d6feff 0%, #3acefa 50%, #0094be 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#d6feff] via-[#3acefa] to-[#0094be]`
- Contrast (worst point): white 1.08:1 fail · black 5.98:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.d6feff-3acefa-0094be?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, #3acefa 0%, #35d5d2 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#3acefa] to-[#35d5d2]`
- Contrast (worst point): white 1.81:1 fail · black 11.36:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.3acefa-35d5d2?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, #3acefa 0%, #faa37f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#3acefa] to-[#faa37f]`
- Contrast (worst point): white 1.80:1 fail · black 10.61:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.3acefa-faa37f?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, #3acefa 0%, #fa95d4 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#3acefa] to-[#fa95d4]`
- Contrast (worst point): white 1.84:1 fail · black 10.28:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.3acefa-fa95d4?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.08:1, black 5.98:1 AA */
  --brand-gradient: linear-gradient(135deg in oklch shorter hue, #d6feff 0%, #3acefa 50%, #0094be 100%);
  /* hero — worst-case contrast: white 1.09:1, black 5.86:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklch shorter hue, #eaf8f8 0%, #9cc3d2 50%, #6c8c9a 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 1.63:1, black 9.91:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #4cdbff 0%, #24c1ec 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #69e4ff 0%, #35cbf7 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #3fd1fd 0%, #05b7e2 100%);
  --brand-gradient-button-ink: #000000;
}
```

## 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.
