## True colors
Using true colors in a terminal emulator means being able to use 24 bits for RGB
colors. That makes 16777216 (2^24) colors instead of the usual 256.
As explained [here](#colorschemes), colorschemes can actually be _two_
colorschemes by having definitions for terminals (xterm) and for GUIs (gvim).
This made sense before terminal emulators learned about true colors.
After `:set termguicolors`, Vim starts emitting escape sequences only understood
by a terminal emulator that supports true colors. When your colors look weird,
chances are your terminal emulator doesn't support true colors or your
colorcheme has no GUI colors defined.
Help: `:h 'termguicolors'`
