Specifying Colors Using Numeric Values
Any color can be specified by using a numeric value which represents the relative amounts of red, green, and blue. These values are specified as a six digit hexadecimal number, preceded by the # character. The first two digits of the number specify the Red value, the next two specify Green, and the final two are for Blue.

Some examples:
  • #000000 - black
  • #0000ff - blue
  • #ff00ff - purple (full red and blue)
  • #777777 - medium gray (equal parts red, green, blue)
  • #cc9903 - yellowish (lots of red, some green, almost no blue)
