Convert between color formats
HEX (hexadecimal) and RGB (Red, Green, Blue) are two ways to represent colors on digital screens. RGB uses three numbers from 0 to 255 (e.g., rgb(255, 0, 0) for red), while HEX uses a 6-digit base-16 code (e.g., #FF0000 for red). They represent the exact same color space.
HSL stands for Hue, Saturation, and Lightness. Hue is a degree on the color wheel (0 to 360), Saturation is the intensity of the color (0% to 100%), and Lightness is the brightness (0% is black, 50% is the pure color, and 100% is white). It is popular in web design because it is easy for humans to adjust.
Screens use the RGB color model (additive color, adding light to black), while physical printers use the CMYK color model (subtractive color, adding ink to white paper). CMYK stands for Cyan, Magenta, Yellow, and Key (Black). Colors must be converted to CMYK before printing to avoid color shifts.
