Define What Each of the Color Selection Areas are in Default/Custom settings

I get totally boggled by the sheer number of items for which we can choose the color in the magazine theme. This seems to be yet another of the themes that does not have a pdf manual? Is there any place that shows, visually, what each of the color picker blocks in the theme options corresponds to? It is very, very time consuming to keep bouncing back and forth, trying out a color and seeing what it affects, how they work together, etc. Would be much, much easier to have a diagram saying this is the “featured image wrapper” and this is the “post date background”, etc, etc.

Any help with such a document or list?
