Color Converter

Free Online Color Converter

Color is represented differently across various contexts — web designers use HEX codes, CSS developers use RGB and HSL, and image processing tools use HSV. This color converter lets you switch between all four formats instantly. HEX codes are six-digit hexadecimal values (#RRGGBB) commonly used in HTML and CSS. RGB specifies colors as red, green, and blue components each ranging from 0 to 255. HSL (Hue, Saturation, Lightness) is more intuitive for humans — hue determines the color type, saturation controls intensity, and lightness adjusts brightness. HSV (Hue, Saturation, Value) is similar but uses "value" (brightness) instead of lightness, making it popular in image editing software. The live preview updates instantly as you modify any value, showing exactly what the color looks like.

How Color Conversion Works

The conversion between color spaces follows standard mathematical formulas. HEX to RGB splits the six-digit code into three two-digit components and parses them as hexadecimal integers. RGB to HSL involves normalizing RGB values to 0-1, finding the min and max to determine lightness and saturation, and calculating hue based on which color component is dominant. HSV differs from HSL in how saturation and value/brightness are calculated — HSV's saturation depends on the maximum component while HSL's saturation depends on the range between min and max.
