Documentation
What does this tool do?
A color transparency matrix utility that transforms any solid base color into a complete 0% to 100% alpha transparency scale. Generates modern CSS `rgb(r g b / a)`, `hsl(h s l / a)`, 8-digit Hex (`#RRGGBBAA`), and Tailwind arbitrary opacity class values (`bg-opacity-50`, `color/50`).
When should you use it?
Use this tool when building glassmorphic overlays, subtle modal backdrop scrims, translucent card borders, hover states, or dark-mode surface tint scales.
