# MongoDB gradient

Gradients derived from MongoDB'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/mongodb-com · Brand page: https://brandsweets.com/b/mongodb-com

## Brand gradient

- CSS: `linear-gradient(135deg in oklab, #00ed64 0%, #006cfa 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#00ed64] to-[#006cfa]`
- Contrast (worst point): white 1.58:1 fail · black 4.53:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.00ed64-006cfa?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 (4.69:1) without adjusting L.

- CSS: `linear-gradient(135deg in oklab, #a1d5a8 0%, #5b78a7 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#a1d5a8] to-[#5b78a7]`
- Contrast (worst point): white 1.67:1 fail · black 4.69:1 AA · banding medium · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.a1d5a8-5b78a7?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 10.62:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #2ffb71 0%, #00df57 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#2ffb71] to-[#00df57]`
- Contrast (worst point): white 1.39:1 fail · black 11.69:1 AA · banding high · ink #000000
- Maker: https://brandsweets.com/gradients/new/v1.2ffb71-00df57?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #41ff7b 0%, #00ea61 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #13f067 0%, #00d54c 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #d9ffde 0%, #00ed64 50%, #00af32 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#d9ffde] via-[#00ed64] to-[#00af32]`
- Contrast (worst point): white 1.09:1 fail · black 7.18:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.d9ffde-00ed64-00af32?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, #00ed64 0%, #bbd500 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#00ed64] to-[#bbd500]`
- Contrast (worst point): white 1.57:1 fail · black 12.61:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.00ed64-bbd500?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, #00ed64 0%, #ff9dfb 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#00ed64] to-[#ff9dfb]`
- Contrast (worst point): white 1.58:1 fail · black 10.96:1 AA · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.00ed64-ff9dfb?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, #00ed64 0%, #aec4ff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#00ed64] to-[#aec4ff]`
- Contrast (worst point): white 1.57:1 fail · black 12.10:1 AA · banding high
- Maker: https://brandsweets.com/gradients/new/v1.00ed64-aec4ff?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 1.58:1, black 4.53:1 AA */
  --brand-gradient: linear-gradient(135deg in oklab, #00ed64 0%, #006cfa 100%);
  /* hero — worst-case contrast: white 1.67:1, black 4.69:1 AA; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #a1d5a8 0%, #5b78a7 100%);
  --brand-gradient-hero-ink: #000000;
  /* button — worst-case contrast: white 1.39:1, black 11.69:1 AA */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #2ffb71 0%, #00df57 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #41ff7b 0%, #00ea61 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #13f067 0%, #00d54c 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.
