UI Colorgen
UI Colorgen is a web application built with Next.js 16, TypeScript, Tailwind CSS, and Radix UI, designed to simplify shadcn/ui color configuration by providing an interactive interface for listing TailwindCSS colors in multiple formats (hex, rgb, hsl), using a color picker to update CSS variables in real-time, adding custom color variables beyond defaults, selecting initial colors and preferred color formats, generating CSS root variables for theme files, and creating Tailwind color configuration for projects.

About
About UI Colorgen
This specialized tool addresses the complexity of color system setup in shadcn/ui projects where manual CSS variable management becomes error-prone and time-consuming as color schemes evolve. Perfect for design systems teams establishing brand colors across shadcn/ui components, developers implementing client-specific themes in white-label applications, agencies customizing shadcn/ui for multiple clients with different brand guidelines, or any project where efficient color configuration directly impacts development velocity and design consistency.
The TypeScript-heavy codebase (94.8%) provides excellent type safety for color manipulation operations, while the multi-format color display helps developers work with colors in their preferred format whether designing in Figma (hex), working with CSS (hsl), or integrating with existing systems (rgb). By generating ready-to-use CSS variables and Tailwind configurations, UI Colorgen eliminates the manual translation between design decisions and code implementation, reducing errors and enabling rapid theme iterations that respond to design feedback or A/B testing results.

Frequently asked questions
Everything you need to know before you ship with UI Colorgen.
UI Colorgen is a web application built with Next.js 16, TypeScript, Tailwind CSS, and Radix UI, designed to simplify shadcn/ui color configuration by providing an interactive interface for listing TailwindCSS colors in multiple formats (hex, rgb, hsl), using a color picker to update CSS variables in real-time, adding custom color variables beyond defaults, selecting initial colors and preferred color formats, generating CSS root variables for theme files, and creating Tailwind color configuration for projects. It is an open source template in the shadcn.io collection of 215.
UI Colorgen is made by Mickasmt, an independent developer; shadcn.io lists it but did not make it. Mickasmt has 5 templates in the collection, and the author's page lists them.
The listing tags UI Colorgen with Next.js, React, Tailwind and Radix UI. Those are its categories, not a dependency list: the exact packages and versions are in the repository's package.json.
Yes. The UI Colorgen page embeds its live demo from ui-colorgen.vercel.app, and links to it so you can open the real deployment before you clone.
The UI Colorgen listing was last updated on October 8, 2025. That date is the listing's, not the repository's: check the repository's commits for recent activity.
Clone the repository (git clone https://github.com/mickasmt/ui-colorgen), then follow the README. The UI Colorgen page shows the usual steps and a terminal block with the commands to copy.
Install dependencies with npm install or pnpm install, then run npm run dev. The README in the UI Colorgen repository says which package manager and environment variables it needs.
No. UI Colorgen is cloned from its own GitHub repository, so shadcn.io isn't involved. Browsing the page and its live demo need no account either; Pro adds the premium templates, the blocks and the MCP server.
UI Colorgen is tagged Next.js, so it deploys wherever a Next.js app does, such as Vercel, a Node.js server or a container. Its README may add steps for its own services.
The UI Colorgen listing doesn't record a license. Check the LICENSE file in its repository (https://github.com/mickasmt/ui-colorgen), and ask the author if there isn't one.
That depends on UI Colorgen's license in its repository, which shadcn.io does not set. Read the LICENSE file before you use it in a client or paid project, and ask the author if it is unclear.
Attribution follows UI Colorgen's license. Many permissive licenses ask you to keep the copyright notice and license text in your copy; its LICENSE file says exactly what.
No. The Pro license covers shadcn.io's own Pro code, blocks and premium templates. UI Colorgen is the author's project, under the terms in its repository.
Mickasmt supports UI Colorgen, through its GitHub repository: read the docs, open an issue or look for discussions. shadcn.io does not maintain it.
Yes. Once you clone it, UI Colorgen is your own code: change the theme, add pages and connect your backend. It uses shadcn/ui, so you can also add more components the same way.
Yes. Components are free with a free account and the blocks are in Pro; both are copied into your project with the shadcn CLI. Check that UI Colorgen uses Tailwind CSS and the shadcn/ui setup (a components.json) before you add them, and pick the base library your project already uses.
Yes, with Pro. The shadcn.io MCP server's search_templates tool finds templates by what they are, and returns each one's repository and live demo, so your editor can set up UI Colorgen for you. Your files stay on your machine.
The collection has 29 other open source Radix UI templates like UI Colorgen, shown at the foot of its page with the ones sharing most categories first. All of them are at /template/category/radix-ui.
Mickasmt has 4 other templates in the collection, including Next SaaS Stripe Starter, Astro Nomy and Next Auth Roles Template. The author's page lists them all.
Yes. The 14 premium templates (Solaris, Reframe Labs, Spherule and Max and more) are built by shadcn.io and come with every Pro plan, if you want maintained code with a design file.
