This is a Digital Fundamentals Tutorial that focuses on the basic differences between sRGB, Adobe RGB, ProPhoto color profiles and RGB and CMYK color models. This video is only 12 minutes, and gives a quick overview on how each color space is designed to be used. It also gives a demonstration of how the image color can shift on different priced monitors.

I also have another video on this whole Color Model, Color Space, and Color Profile topic. This can all get very confusing. Not that it needs to be, it's just that even the people teaching it don't know what they are saying. This just opens up a level of cross information, and does not help anybody.
