Evey -- the BBcode colours are exactly the same as HTML colours, even down to the comment mark prefix. Basically, a 2-digit hex number each for the amount of red, green and blue light. [color=#5959ab]looks like this[/color].
Hex counting works like this: after 9 comes "a" (10 in decimal), then "b", "c", "d", "e", "f"; then 10 is 16 in decimal. The last digit is the units; the one before that is the sixteens. Using 2 hex digits you can count up to 255 decimal, then 256 is 100 in hex. It's useful in computing, because it's very, very easy to convert hex to binary; one hex digit (which can have any of 16 values, 0 to f) is directly equivalent to four binary digits which also have 16 possible values between them. And binary digits tend to hang around in multiples of 8 anyway .....
