<< What does this theory of carotene pigments in the plastids say about how
 much pigment can be there?  Do plastids come in different sizes, making
 it possible to have more pigment by having more or bigger plastids?  Or
 are the color differences (differences in color intensity/depth/darkness
 or whatever we are calling it) thought to be due to the presence of
 different pigments?  Or both?

I don't recall seeing anything about the size of the plastids, but rather 
have the impression that it is their number that is significant -- with the 
differences in intensity explained by their varying densities and the hue by 
the mixture present in a specific cultivar.
