Why we built this theme generator

Most theme tools are bloated. We just wanted something clean, accessible and efficient — built on solid design principles.

Radix Colors as a foundation

We use Radix Colors as the backbone of this system. Their accessible and consistent palettes are perfect for building modern themes across light and dark modes, with clean semantic scales.

Simple by design

Most theme generators are full of endless options. Ours gives you solid, clean defaults and opinionated logic — so you get results fast, without getting lost in complexity.

Tailored for shadcn/ui

This tool was built for shadcn/ui and Tailwind CSS. The generated themes drop right into your project — without config headaches or manual overrides.

Who’s behind this?

This tool was built by mandalor.studio, a small team crafting custom tools and projects. We focus on simplicity, performance, and real-world usefulness.
