Answer 1

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 2

I'm using gnome terminal and this solved the problem, but (0) don't forget to:

killall tmux

(1) Edit .tmux.conf

# 24 bit color
set -g default-terminal "tmux-256color"
set -ga terminal-overrides ",*256col*:Tc"

(2) Edit: .vimrc

" Enable true color
if exists('+termguicolors')
  let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
  let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"
  set termguicolors
endif

Answer 3

From the tmux man page, adding flag as following:

tmux -2

This -2 flag forces tmux to run on 256-color mode.

This works for me

Answer 4

If you use tmuxinator or mux, you will 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'

These forces to use 256-color in terminal.

Then tmux, tmuxinator and mux command will all work.

Answer 5

I have tried all of the instructions above, and I found out the most important thing is I have to explicitly add the following line in my .bashrc file.

export TERM=screen-256color

I don't know why alias tmux="TERM=screen-256color-bce tmux" doesn't work out. I use Sierra 10.12.1.

Answer 6

If you find yourself in the same sitation as me, that none of the above worked.. try this:

in .tmux.conf:

set -g default-terminal "xterm"

in bash config (maybe .bashrc or .bash_profile):

alias tmux="tmux -2"

and then run:

killall tmux

and then relaunch tmux
