The 8 bit RGB model uses 3 bits for red, 3 bits for green and only 2 bits for blue (not green as I thought in class). If you want, read about the biological basis for this (scroll halfway down the page.)
Below are examples of 8, 16, and 24 bit color (taken from here). (Of course, the last two may look the same to you. Why is that? I leave that for your discussion. Hint: click on them to see a bigger image.)

I was just looking online and apparently some video projectors *reduce* the color depth of images during processing (to make the processing faster.) (The projector in 204/5 clearly is doing processing because the aspect ratio of the video image is changed as it is being projected)
This extra processing is common because the resolution of most of these projectors is lower than the screen resolution resulting in scan conversion
