The theme attempts to reduce the usage of colors to a minimum based on my personal preferences. It's not fully monochrome, for example diffs and active regions are distinguished via colors. The theme assumes no font-lock, i.e. (global-font-lock-mode 0), so there is very little customization for syntax aware faces. The used colors are from the base16 set that is available at: https://github.com/chriskempson/base16 set.
