CSS Color Codes

Color codes in css are written in hexadecimal form.

CSS colors are defined using a hexadecimal (hex) notation for large combinations of colors. Red, Green, and Blue color values (RGB) are represented with different strengths. The lowest light source value is 0 (hex 00), and the highest value is 255 (hex FF).

Hex entries must be either 3 or 6 characters:
( #fff or #ffffff ) ( #147 becomes #114477 )
