# Calendly gradient

Gradients derived from Calendly'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 colors: https://brandsweets.com/colors/brands/calendly-com · Brand page: https://brandsweets.com/b/calendly-com
- Palette: primary #64acfb, secondary #d4c2ff, accents #c3dffe

## Brand gradient

- CSS: `linear-gradient(135deg in oklab, #64acfb 0%, #d4c2ff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#64acfb] to-[#d4c2ff]`
- Contrast (worst point): white 1.62:1 fail · black 8.84:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.64acfb-d4c2ff?a=135

## 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 (8.88:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #93abc6 0%, #d0cadf 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#93abc6] to-[#d0cadf]`
- Contrast (worst point): white 1.59:1 fail · black 8.88:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.93abc6-d0cadf?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. Black ink passes AA on the surface and both states (worst 6.80:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #71b9ff 0%, #589fed 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#71b9ff] to-[#589fed]`
- Contrast (worst point): white 2.08:1 fail · black 7.60:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.71b9ff-589fed?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #80c3ff 0%, #61a9f8 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #67affe 0%, #4e96e3 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #c3e5ff 0%, #64acfb 50%, #2b74be 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#c3e5ff] via-[#64acfb] to-[#2b74be]`
- Contrast (worst point): white 1.31:1 fail · black 4.34:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.c3e5ff-64acfb-2b74be?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, #64acfb 0%, #23b9e2 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#64acfb] to-[#23b9e2]`
- Contrast (worst point): white 2.30:1 fail · black 8.80:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.64acfb-23b9e2?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, #64acfb 0%, #e1961e 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#64acfb] to-[#e1961e]`
- Contrast (worst point): white 2.38:1 fail · black 8.20:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.64acfb-e1961e?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, #64acfb 0%, #fb788d 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#64acfb] to-[#fb788d]`
- Contrast (worst point): white 2.37:1 fail · black 8.14:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.64acfb-fb788d?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.62:1, black 8.84:1 AA */
  --brand-gradient: linear-gradient(135deg in oklab, #64acfb 0%, #d4c2ff 100%);
  /* hero — worst-case contrast: white 1.59:1, black 8.88:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #93abc6 0%, #d0cadf 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 2.08:1, black 7.60:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #71b9ff 0%, #589fed 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #80c3ff 0%, #61a9f8 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #67affe 0%, #4e96e3 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.
