Each code is made up of 3 main parts. Red, Green, and Blue.

rrggbb
123456

Each part represents a number from 0 to 255. The higher the number, the more of this color that is displayed. 0 = no color; 255 = full color. To fit these numbers into a 2-digit code, the counting system is changed a bit. Instead of 0 through 9, it is 0-9 and then a-f. a-f represents 10-15. So...

Using that chart, you can create 256 shades of red, green, and blue. Combine that together, and you can make 16,777,216 different colors. To do this, take the shade of red, green, and blue you want and combine the codes (2-digit) into a single code (6-digit). The order should be red, green, then blue. For example...

Red:   256 ff
Green: 102 66
Blue:    0 00
Final: ff6600
