lose vim colorscheme in tmux mode

I'm running iterm2 and when I'm in tmux mode the colorscheme I have set in vim does not show up. Only the color scheme I've set in iterm. If I run vim from shell the colorscheme appears correct - its only when I'm in tmux mode.

I've tried setting :colorscheme molokai when in vim (see screenshot below) and it doesn't change - again, the default colorscheme for iterm2 remains.

Am I missing some setting to iterm or tmux.conf? My dotfles are up on github here.

Any help would be grand :)

As @romainl mentions above, I needed to force tmux to use 256 colors by adding the -2 flag:

$ tmux -2

I added alias tmux='tmux -2' to my bash_profile so I don't forget :)

I had the same problem. Only difference was I am using solarize rather then molokai.

To fix the issue, I have set up an alias in ~/.bashrc:

alias tmux="TERM=screen-256color-bce tmux"  

And set up the default-terminal option in ~/.tmux.conf:

set -g default-terminal "xterm"  

Lastly, do $ source ~/.bashrc to load new alias.

So this a bit on the stale side, but it's might be worth mentioning that using screen will often break the Home and End keys. Using

export TERM="xterm-256color"  

in should keep the functionality of these and allow the color scheme (or powerline) to work fine.

I tried all the solutions above and what finally worked for me is just putting the following line in .tmux.conf :

set -g default-terminal "xterm-256color"

Answer by Patrick Lewis for lose vim colorscheme in tmux mode

I didn't have much luck trying to export a different TERM or set default-terminal in my .tmux.conf.

My solution for fixing vim colors within tmux was adding this line to .tmux.conf:

set -g terminal-overrides 'xterm:colors=88'

I'm not sure why this override was needed given that my TERM=xterm and I have iTerm set to xterm as well, but it seems to work.

Answer by Chev for lose vim colorscheme in tmux mode

I just discovered why I was having a lot of confusion. I, like others here, was having a difficult time getting the default-terminal setting to take effect. I remembered that I had a tmux session in the background. I re-attached my session, closed out my processes, and closed ALL tmux processes. The next time I restarted tmux the default-terminal setting in .tmux.conf began to take effect. I don't know if others are doing this as well but I recommend closing all tmux processes before modifying the .tmux.conf file.

I got my setup to work on my local machine (OSX 10.9.5 with iTerm2) without any modification to .bashrc or .bash_profile. All I did was add the line set -g default-terminal "xterm-256color" to ~/.tmux.conf and restarted all tmux processes.

I got my remote setup (ssh to Ubuntu 14.04) to work exactly the same way without any modifications to .bashrc. I simply added set -g default-terminal "xterm-256color" to ~/.tmux.conf on my remote machine and restarted all remote tmux processes.

You can test what Vim is seeing by doing echo $TERM from within a tmux session. It kept saying screen as the value until I restarted all tmux processes, at which point it reflected xterm-256color as expected.

Hope that helps.

From the tmux man page, adding flag as following:

tmux -2

This works for me

Answer by Andrew Johnston for lose vim colorscheme in tmux mode

I needed vim to display correctly with tmux in terminal on ubuntu and cygwin/mintty on windows. I got it to work by combining the answers like this.

In .bashrc:

alias tmux="tmux -2"  

In .vimrc:

" use 256 colors in terminal  if !has("gui_running")      set t_Co=256      set term=screen-256color  endif    " fix cursor display in cygwin  if has("win32unix")      let &t_ti.="\e[1 q"      let &t_SI.="\e[5 q"      let &t_EI.="\e[1 q"      let &t_te.="\e[0 q"  endif  

based on answers from this question, this Vim wiki page and this block cursor question

If you use tmuxinator,you need to add these in .bashrc or .zshrc:

alias tmux='TERM=screen-256color tmux -2'  alias tmuxinator='TERM=screen-256color tmuxinator'  alias mux='TERM=screen-256color mux'  

Then tmux ,tmuxinator and mux command all work.
