What Is a Color Converter?
A color converter translates a color from one format to another, such as HEX to RGB or RGB to HSL. Web designers and developers constantly move between these formats because CSS supports several notations, and design tools often export colors in a specific one. A color converter lets you paste a value and instantly see the equivalent in the other formats, along with a live preview swatch.
HEX, RGB, and HSL Explained
- HEX: A six-digit hexadecimal value beginning with a hash, such as #2563eb, where each pair represents red, green, and blue.
- RGB: Three numbers from 0 to 255 describing the red, green, and blue channels, such as rgb(37, 99, 235).
- HSL: Hue, saturation, and lightness, which describes a color more intuitively for designers, such as hsl(221, 83%, 53%).
How Color Conversion Works
Converting HEX to RGB is straightforward: each pair of hex digits is parsed as a base-16 number. Converting RGB to HSL requires finding the maximum and minimum channel values to compute lightness and saturation, then calculating hue based on which channel is dominant. The reverse conversion uses standard hue-to-channel formulas.
When to Use Each Format
HEX is compact and widely used in CSS. RGB is ideal when you need to control opacity with an alpha channel. HSL is friendlier for building themes because you can adjust lightness or fill independently. A color converter makes it easy to switch between them as your project evolves.
