Frequently Asked Questions

What color formats are supported?

The tool supports HEX (#RRGGBB), RGB (0-255 per channel), HSL (hue 0-360, saturation/lightness 0-100%), RGBA (RGB with alpha transparency 0-1), and HSLA (HSL with alpha transparency). All formats update in real-time when you change any value.

How does the Tailwind color matching work?

The tool compares your selected color against the full Tailwind CSS color palette and finds the closest match by calculating the color distance. It suggests the nearest Tailwind class name like 'blue-500' or 'red-400' for quick use in your Tailwind projects.

What is the difference between RGB and HSL?

RGB defines colors by Red, Green, and Blue channel intensities (0-255). HSL defines colors by Hue (color wheel position, 0-360°), Saturation (color intensity, 0-100%), and Lightness (brightness, 0-100%). HSL is often more intuitive for adjusting colors - for example, making a color lighter or more muted.

What is RGBA and when should I use it?

RGBA adds an Alpha (transparency) channel to RGB, with values from 0 (fully transparent) to 1 (fully opaque). Use RGBA when you need semi-transparent colors in CSS - for example, overlay backgrounds, shadow colors, or fading effects. The tool converts between RGBA and HSLA formats as well.

Is this color code converter free?

Yes, completely free with no signup. Convert between HEX, RGB, HSL, RGBA, and HSLA instantly. Use the visual picker, find the closest Tailwind class, and check contrast ratios - all in your browser with no data sent to any server.
