Colors

Web colors are specified by HEXADECIMAL code which describes the RGB value. RGB stands for RED GREEN BLUE. These are the primary colors that make up all other colors. The hexadecimal code includes two characters for each color. Hexadecimal codes have the format: #RRGGBB
Examples: White = #FFFFFF, Black = #000000, Red = #FF0000, Green = #00FF00
Browsers greater than version 3 can also correctly process 256 named colors (red, white, black, purple, periwinkle, etc.)
