Hex color codes
The most popular are Hex color codes; three byte hexadecimal numbers (meaning they consist of six digits), with each byte, or pair of characters in the Hex code, representing the intensity of red, green and blue in the color respectively.
Hex code byte values range from 00, which is the lowest intensity of a color, to FF which represents the highest intensity. The color white, for example, is made by mixing each of the three primary colors at their full intensity, resulting in the Hex color code of #FFFFFF.
