Summary
A straightforward color utility server that plugs into Claude via Cloudflare Workers. You get color conversions (hex, RGB, HSL), harmony generation (complementary, triadic, analogous, split, tetradic, monochromatic), gradient interpolation, and WCAG contrast checking. It can also spit out CSS variables or Tailwind config from color arrays. Useful when you're building UIs in a conversation and need to generate accessible palettes, check contrast ratios, or export design tokens without switching to Figma or a color picker. The free tier works for light use, and there's a Pro plan if you need higher rate limits across the lazymac API suite.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
