If you have a number representing a color, say 8438015 (teal
blue), then you can use the integer divide and Mod operators to
extract the red, green and blue components, like so:
Red = 8438015 \ 256^2 mod 256
Green = 8438015 \ 256^1 mod 256
Blue = 8438015 \ 256^0 mod 256
which turns out to be Red = 128, Green = 192 and Blue = 255, or
in hexadecimal: Red = &H80, Green = &HC0 and Blue = &HFF.
Note also that Windows colors (as in Visual Basic) are packed in
the opposite order as Blue, Green, and Red, but otherwise the
same formula holds.
Going the other way, it's just Color = Red*256^2 + Green*256 +
Blue
