About HEX and RGB

HEX colors are six hexadecimal digits — two each for red, green, and blue — usually prefixed with #. A three-digit shorthand doubles each digit, and an optional fourth pair adds alpha, so #7c3aed80 is the same purple at half opacity.

RGB lists red, green, and blue as numbers from 0 to 255, matching how screens mix light. It's the format most APIs, canvas code, and design tools expect, and rgba() adds an opacity value from 0 to 1.

For example, #7c3aed in HEX is rgb(124, 58, 237) in RGB. Paste your own value above — conversion is instant, runs entirely in your browser, and carries alpha through when your color has one.
