Hey HN,

I'm 16 and built this after over-engineering my first SaaS and never shipping.

Huesly generates complete design systems (colors, fonts, spacing) from a mood in <1 second. Uses OKLCH color space for actually harmonious palettes instead of random RGB.

Tech stack: - Next.js 15 - TypeScript - PostgreSQL - Tailwind CSS

Export formats: - CSS variables - Tailwind v4 config - SCSS - JSON tokens

Homepage has a live demo that updates every 3 seconds so you can see the possibilities.

Built in 2 weeks to force myself to ship fast instead of perfecting infrastructure.

Happy to answer any questions about the color science, architecture, or why OKLCH > RGB.
