This would paint the background of the editor red. See `:h :highlight` for more
information.
So, colorschemes are mostly a collection of `:highlight` commands.
So, colorschemes are mostly collections of `:highlight` commands.
Actually, most colorschemes are really 2 colorschemes! The example above sets
colors via `ctermbg` and `guibg`. The former definition will only be used if Vim
was started in a terminal emulator, e.g. xterm. The latter will be used in
graphical environments like gVim or when you enable true colors (24bits) support
in terminal Vim by using `set termguicolors`.
colors via `ctermbg` and `guibg`. The former definition (`cterm*`) will only be
used if Vim was started in a terminal emulator, e.g. xterm. The latter (`gui*`)
will be used in graphical environments like gvim or MacVim.
If you ever happen to use a certain colorscheme in Vim running in a terminal
emulator and the colors don't look like the colors in the screenshot at all,
chances are that the colorscheme only defined colors for the GUI _in case of
older Vim versions_ or in can you are running Vim `7.4.1830` or Neovim you
didn't enable true colors in your `.vimrc`
If you ever happen to use a colorscheme in terminal Vim and the colors don't
look like the ones in the screenshot at all, chances are that the colorscheme
only defines colors for the GUI. Conversely, if you use a graphical Vim (e.g.
gvim or MacVim) and the colors look off, the colorscheme might only define
colors for the terminal.
Many people think that running Vim in the terminal won't give you nice color
support for themes like normal editors, but this is not the case anymore.
For more info on this you can check `:h termguicolors`.
I use [gruvbox](https://github.com/morhetz/gruvbox) for the GUI and
[janah](https://github.com/mhinz/vim-janah) for the terminal.
The latter case can be "solved" by enabling true colors in Neovim or Vim
7.4.1830 and newer. This makes terminal Vim use the GUI definitions instead, but
also requires the terminal emulator itself and all software in between (e.g.
tmux) to be capable of handling true colors. ([This
gist](https://gist.github.com/XVilka/8346728) gives a good overview about the
topic.)
