It depends on what you define as a "Color". There are 256 * 256 * 256 visible colors, and and 256 levels of opacity. So 32bit color is really the same as 24bit color except that it has 8 extra bits to define the opacity.

32 bits hold can a value of up to 4294967296. In terms of colours it's not quite that simple and also depends if you're using INT or FP representation.

32-bit color has two parts to it:

color is support by the first 24 bits

translucency per shade of color is supported by the last 8 bits


So do 2^24 in your calculator and you'll get your answer. I don't have a calculator with me right now. But It's supposted to be like 16.7million colors.

Oh wait. another way of doing it is. 8 bits for each primary color: red, blue, green. 8 bits = 256 combinations per color. So multiply 256 x 256 x256 and it will give you 16.7million colors. If you want to factor in the transulcency multiply in another 256.
