Section B.1. Color values
B.1. Color values
On the Web, colors are displayed by mixing red, green, and blue (RGB) light. Values range from 0 to 255 and can be written as such (e.g., rgb(5,233,70)), but they are more commonly written in hexadecimal. Colors written in hex consist of a hash sign (#) followed by six digits. The six digits are made up of pairs, representing the red, green, and blue color values, respectively.
#XXxxxx: Red color value
#xxXXxx: Green color value
#xxxxXX: Blue color value
