This has to do with 256 colors. Older terminals only supported 8 or 16 colors. Even now, some Terminals (and terminal emulators) may have to be told explicitly to use 256 colors even if they support it. (xterm does). If you use an emulator like tmux, you’ll have to tell tmux as well to use 256 colors.
This has happened to me on an Armbian system. The same Vim colorscheme that looked classy on macOS refused to work on Debian. Turns out Vim needs to be told to use 256 colors. Then it worked in xterm, but the ugliness continued when i’d open Vim inside tmux, so i had to set 256 color settings to tmux as well.
1# ~/.vimrc
2t_Co=256
3
4# ~/.tmux.conf
5set -g defalt-terminal "screen-256color"
You can also open tmux with 256 colors using the -2 flag:
1# -2 Force tmux to assume the terminal supports 256 colours.
2tmux -2
tmux an alias to tmux -2echo $TERM to see what Terminal you havet_Co=256 let’s Vim use 256 colors in Terminals that support it. Without it Vim will only show 8 or 16 different colors. I needed to add this on an Armbian setup in order for the Monokai theme to work.
