What is Color Converter?
A color converter takes a hex color and converts it to RGB, HSL, HSV and CMYK, showing a color swatch and all common formats.
Color models
HEX and RGB describe colors as red/green/blue intensities. HSL and HSV describe hue, saturation and lightness/value, which are more intuitive. CMYK is used for printing.
Why convert?
Different tools and contexts require different formats. CSS uses HEX, RGB or HSL; design apps may use HSV; printers use CMYK.
