Theming

Bilal UI uses Tailwind CSS v4 and CSS Variables for theming. To ensure components look correct in your project, you must define the following variables in your global CSS file.
Color Variables

Copy these variables into your global CSS file (usually app/globals.css or src/index.css). We use OKLCH color space for better gamut and accessibility.
app/globals.css
@import "tailwindcss";
