Color Code Converter (HEX/RGB/HSL)

Switching a color between HEX, RGB, and HSL is a routine need for designers, developers, and digital artists, and this converter moves cleanly among all three. As of 2026, with augmented reality interfaces spreading and display technologies such as micro-LEDs maturing, defining color precisely and adapting it across very different screens has only grown more important to keeping a visual experience consistent.

Each direction follows a settled algorithm. Going from HEX to RGB means reading the hexadecimal pairs and translating each into its decimal value for the red, green, and blue channels. Moving from RGB to HSL runs a short chain of calculations off the largest and smallest of the RGB values, which yields hue as an angle on the color wheel, saturation as intensity, and lightness as brightness.

Two details trip people up. HSL saturation and lightness are expressed as percentages rather than the absolute 0-to-255 scale that RGB uses, so they cannot be read interchangeably. HEX input also needs to land on either 6 characters, like #FF0000, or the 3-character shorthand, like #F00, for the parser to handle it. Feed the converter a mismatched format and the output will be wrong.
