Hex color codes are the way web colors are specified, encoding the red, green, and blue components in base 16. A code like #ffcc99 has six digits: the first pair (ff) is red, the second pair (cc) is green, and the third pair (99) is blue. In decimal, that’s red 255, green 204, blue 153. These codes are used in HTML/CSS to apply exact colors to elements on the web. Other options describe color in different systems: CMYK is used for printing, RGB color mode is a general device color model, and HSL describes color by hue, saturation, and lightness. So the hex notation shown is specifically the web color hex representation.
