# 256 color support for vim background in tmux

colorstmuxvim

while using vim within tmux I can see that 256 color support is enabled. with $tput colors However changing the colorscheme in vim while in tmux will change the colorscheme on a per line basis but not the entire background. see screenshot Here is a snippet of the my .vimrc file for example. My original colorscheme is solarized dark and then after running :colorscheme molokai you see what happens. info • gnome-terminal • bash in my ~/.tmux.conf  set -g default-terminal "screen-256color"  in my ~/.vimrc  set t_Co=256  in my ~/.bashrc # ryan export TERM="xterm-256color" # ryan alias tmux="tmux -2"  in my ~/.profile # ryan 256 color support if [ -e /usr/share/terminfo/x/xterm-256color ]; then export TERM='xterm-256color' else export TERM='xterm-color' fi  Any ideas how I can get a full colorscheme change in vim? Are all my snippets from the files looking good? #### Best Answer From the look of your .bashrc and .profile, the shells inside tmux are overriding the 'default-terminal' setting in your tmux conf. Something like this: • tmux creates new shell with TERM=screen-256color • .bashrc/.profile run, set TERM=xterm-256color • vim runs, tries to use incorrect TERM for tmux you can check this by running echo$TERM


in a fresh tmux shell.

Tmux is relatively picky about having a terminal set correctly. If you can, set the term value in gnome-terminal's configuration, not in your .bashrc. Failing that, surround those settings with a check for "screen" or "screen-256color" TERM, and don't reset them in that case.

Tmux REALLY wants the terminal set to screen or screen-256color
