Scanners use RGB -- which means that there are printed colors they
won't deal with.

I did not mean any insult by "narrow" -- only that there are many
color models, not just RGB, and RGB is neither the best nor the most
powerful model.

Only so long as you aren't doing work that requires accurate color in
a subtractive color environment, such as printing. Otherwise you'll
discover why Photoshop does CMYK, and why the manual chapter on that
topic is so long and complex.
