};About this tool
Setting up a cohesive design system in Tailwind CSS takes hours of manually picking hex codes for a 50-900 color scale. This tool uses HSL color math to automatically generate a perfect, consistent UI palette from just a single brand color. It outputs a complete `tailwind.config.js` file with custom colors, typography, and border radii, ready to be dropped directly into your Next.js or React project.

Frequently asked questions
How does it calculate the 50-900 shades?
It converts your hex color to HSL (Hue, Saturation, Lightness), keeps the Hue and Saturation mostly constant, and algorithmically adjusts the Lightness percentage to create a smooth, consistent gradient across all 10 shades.
Does it work for grayscale brands?
Yes. If your input color has very low saturation (like #111111), the generator detects it and produces a pure grayscale palette.
What version of Tailwind is this for?
The output config format is compatible with Tailwind CSS v3.x, utilizing the `theme.extend` object for safe merging.
