UI Colors
Hey all! 👋
Erik here, the maker of uithemes.app.
If you’ve never used shadcn/ui, it’s a popular UI component set for React developers. It gives you beautifully crafted components, but with a very neutral minimal theme. That neutral look is intentional, but it also means your app can look a bit flat unless you customize it.
The problem
Customizing shadcn/ui is not easy. The theme is controlled by a long list of CSS variables, and most existing “theme generators” just expose those variables in a giant form. You still need solid design knowledge to create a cohesive, accessible theme. For many people, that is a huge barrier. Even designers spend hours tweaking everything.
🤝 Meet UI Themes
uithemes.app uses the same algorithmic color engine behind uicolors.app to generate complete shadcn/ui themes from:
A custom palette created from a single brand color
Any default Tailwind CSS palette
Pick a color and uithemes.app automatically does the hard work for you. The result is a cohesive, polished, and accessible theme without needing color theory knowledge.
🎲 Beautiful themes in seconds
Hit the Random button to instantly generate a unique theme. Because the engine understands how colors work across the UI, the results are almost always usable right away. What used to take hours now takes only a few seconds.
👀 Preview, export, and share
Live preview of shadcn/ui components and dashboard
Export your theme instantly
Share a public theme link with clients or teammates for quick feedback
✨ Why this matters
Designing a theme should not require deep design expertise. uithemes.app turns a slow, design-heavy task into something fast, reliable, and fun, while still delivering professional-quality results.
I’d love to hear your feedback and ideas. I’m actively improving the tool based on what the community needs.
Is it down?
whooaaa it's what I need. not used yet, but I'll update later. I'm using AntD components too in the same project, fingers crossed.
Do you consider creating a config generator for AntD?

@steveselcuk Great! I’m not familiar with AntD yet, but if there’s clear demand for it, I’ll definitely explore support for it.
I use your UI Colors app all the time, and love it! I'm excited to have this new tool to make my work even easier. It looks beauuuutiful - your design talent is insane. Cheers and congrats on the launch!
