ChromaBrew — Free Design System Tool
Turn one brand color into a complete design system.
What it does
Turn one color into a complete design system: accessible palettes, semantic tokens, light and dark themes, WCAG checks, and production-ready CSS, Tailwind v4 and shadcn/ui exports. Free, no account required.
Generate accessible palettes, semantic tokens, light and dark themes, and production-ready code in seconds. No account. No upload. Everything runs in your browser — or explore the individual tools . This dashboard is rendered live from the default example color #47003A. Open the generator to change it and watch every surface, badge and button follow. This is a demonstration modal rendered inline so you can see destructive styling without popups. Scales are generated in OKLCH so every step is evenly spaced to the eye — not arbitrary white/black mixes. Your brand hue survives end to end. Stop shipping raw hex values. Get background, surface, primary, border and status roles that map directly…from chromabrew.com

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
