Color Guide For Theme Editor?

Looking to figure out what some of the color names are in Theme Editor. I check Home, Product, Category, Page, Registration etc trying to see what changes but often can't find them and assume visitors will.

Base - seems to control many random things (backgrounds, borders...) and affects but doesn't use the colors you pick (I chose #ffffff it displays #f2f2f2, I chose #ff0000 it displays #e60000)

Buttons - What are buttons? (Primary Button affects the Quick View link (but not hover), what are secondary and tertiary?)

Sidebar - has no affect on my sidebar...

Decorative - ?
