    32-bit color in Windows environment

    In 3D definition, 32-bit color rendering means 8-bits for each red, green and blue, as well as an additional 8-bits for transparencies (???) right? But how come some graphics card have the option to display 32-bit color in Windows? Human eyes cannot see more than 16 million colors isn't it? So what does 32-bit color do? Display 4.2 billion colors? If so, how many bits for each RGB color then? Or is the additional 8-bits used to speed things up? (I don't see the logic) If anyonw knows the answers to these questions, please let me know. Thanks.

    For the most part 32-bit color is the same as a video card that puts out 200 fps. It needs to sell. We cannot see that many colors, or that many fps, but there has to be something new , or people will not upgrade. I've had people argue with me that they can see the difference in colors, but I guess they're just delusionary. i'v seen good enough palettes that I could not even tell were 256.

    Okay, if it were really 4.2 billion colors, then how many bits for each R,G, and B color?

    32 / 3 = 10.6667 ???

    Obviously that's impossible.

    Or is it 10-bits for Red, 12-bits for Green, and 10-bits for Blue (or similar)???
