Contrary to popular approach of carefully selecting colors based on some idea, the provided themes were made by a few years of trying different color combinations, out of random, just to fit my personal preference.
So far this worked well, at least for me, and my own sense of color. Themes provide 3 basic setups: 2 variations of dark background, and one for light (suitable for sunny days).
I expect to improve those along the time, so please don’t hesisteate to notify me if you see any problem colors or missing package colors defined.
