I am trying to use the solarized color scheme in VIM using gnome terminal (Ubuntu).  When I run vim without tmux, it looks great, see below:If I add the following commands to my .bashrc# tmux configurationtmux attach &> /dev/nullif [[ ! $TERM =~ screen ]]; then    exec tmuxfiand start the terminal with tmux, the colors do not look right, see below:Here is the contents of the .tmux.conf filesource ~/.local/lib/python2.7/site-packages/powerline/bindings  /tmux/powerline.conf                    set-option -g default-terminal screen-256color                                                                                                                                          set-option -g history-limit 10000   I am using https://github.com/altercation/vim-colors-solarized for the vim color scheme, and the terminal is: https://github.com/Anthony25/gnome-terminal-colors-solarized.EDIT:With tmux:~$ echo $TERMscreenWithout tmux:~$ echo $TERMxterm
VIM solarized color scheme looks wrong when using tmux
vim;tmux;gnome terminal
The issue was the tmux version 1.8.  I used advice from here:https://stackoverflow.com/questions/25940944/ugrade-tmux-from-1-8-to-1-9-on-ubuntu-14-04Upgraded tmux to version 1.9a, and the problem went away.
