How do I convert HEX to RGB?

Enter your HEX color code (e.g., #3b82f6) in the HEX input field. The RGB values are automatically calculated and displayed. Each pair of hex digits represents a color channel: RR, GG, BB, where each ranges from 00 to FF (0 to 255 in decimal).

What is the difference between HEX, RGB, and HSL?

HEX uses hexadecimal notation (#RRGGBB) and is the most common format in web development. RGB defines colors by Red, Green, and Blue channel values (0-255). HSL defines colors by Hue (0-360°), Saturation (0-100%), and Lightness (0-100%), which is more intuitive for color adjustments.

Which color format should I use in CSS?

All three formats are valid in CSS. HEX (#3b82f6) is the most widely used. RGB (rgb(59, 130, 246)) is useful when you need to add alpha transparency (rgba). HSL (hsl(217, 91%, 60%)) is best when you want to adjust lightness or saturation programmatically.

Can I use the color picker to select a color?

Yes. Click on the color picker bar below the preview area to open your operating system's native color picker. Select any color and all formats (HEX, RGB, HSL) will update automatically.

Does this tool support transparency/alpha?

The current version supports opaque colors in HEX, RGB, and HSL. Alpha channel support (RGBA, HSLA, HEX8) is planned for a future update.
