# Render gradient

Gradients derived from Render'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/render-com · Brand page: https://brandsweets.com/b/render-com
- Palette: primary #8a05ff, secondary #33acff, accents #8a05ff

## Brand gradient

- CSS: `linear-gradient(135deg in oklab, #8a05ff 0%, #33acff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#8a05ff] to-[#33acff]`
- Contrast (worst point): white 2.48:1 fail · black 3.55:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.8a05ff-33acff?a=135

## Hero background

Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). L shifted −0.16 until the ink passes AA at the worst point (4.64:1).

- CSS: `linear-gradient(135deg in oklab, #463274 0%, #577895 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#463274] to-[#577895]`
- Contrast (worst point): white 4.64:1 AA · black 1.97:1 fail · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.463274-577895?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. L shifted −0.01 so white ink passes AA on the surface and both states (worst 4.66:1).

- CSS: `linear-gradient(180deg in oklch shorter hue, #9322ff 0%, #7c00ec 100%)`
- Tailwind: `bg-linear-to-b/oklch from-[#9322ff] to-[#7c00ec]`
- Contrast (worst point): white 5.37:1 AA · black 3.07:1 AA-large · banding high · ink #ffffff
- Maker: https://brandsweets.com/gradients/new/v1.9322ff-7c00ec?a=180&in=oklch&hue=shorter
- Hover: `linear-gradient(180deg in oklch shorter hue, #993fff 0%, #8400f8 100%)`
- Active: `linear-gradient(180deg in oklch shorter hue, #8a05ff 0%, #7200da 100%)`

## Tonal ramp

- CSS: `linear-gradient(135deg in oklch shorter hue, #b486ff 0%, #8a05ff 50%, #51009f 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#b486ff] via-[#8a05ff] to-[#51009f]`
- Contrast (worst point): white 2.69:1 fail · black 1.85:1 fail · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.b486ff-8a05ff-51009f?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, #8a05ff 0%, #3155ff 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#8a05ff] to-[#3155ff]`
- Contrast (worst point): white 5.41:1 AA · black 3.54:1 AA-large · banding high
- Maker: https://brandsweets.com/gradients/new/v1.8a05ff-3155ff?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, #8a05ff 0%, #6b7800 100%)`
- Tailwind: `bg-linear-to-br/oklch from-[#8a05ff] to-[#6b7800]`
- Contrast (worst point): white 4.86:1 AA · black 3.54:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.8a05ff-6b7800?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, #8a05ff 0%, #a75800 100%)`
- Tailwind: `bg-linear-to-br/oklab from-[#8a05ff] to-[#a75800]`
- Contrast (worst point): white 5.17:1 AA · black 3.55:1 AA-large · banding medium
- Maker: https://brandsweets.com/gradients/new/v1.8a05ff-a75800?a=135

## CSS custom properties (brand.css)

```css
:root {
  /* Brand gradient (derived) */
  /* worst-case contrast: white 2.48:1, black 3.55:1 AA-large */
  --brand-gradient: linear-gradient(135deg in oklab, #8a05ff 0%, #33acff 100%);
  /* hero — worst-case contrast: white 4.64:1 AA, black 1.97:1; ink passes AA at the worst point */
  --brand-gradient-hero: linear-gradient(135deg in oklab, #463274 0%, #577895 100%);
  --brand-gradient-hero-ink: #ffffff;
  /* button — worst-case contrast: white 5.37:1 AA, black 3.07:1 AA-large */
  --brand-gradient-button: linear-gradient(180deg in oklch shorter hue, #9322ff 0%, #7c00ec 100%);
  --brand-gradient-button-hover: linear-gradient(180deg in oklch shorter hue, #993fff 0%, #8400f8 100%);
  --brand-gradient-button-active: linear-gradient(180deg in oklch shorter hue, #8a05ff 0%, #7200da 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.
