Terminal 256 colors don't work through Tmux

Getting 256 colors to work in tmux

I want to set my terminal to 256 colors. I normally use the Gnome terminal which is shipped by default in Ubuntu but I also downloaded Terminator and tried Xterm and all them return 8 when I call tput color inside Tmux.

How can I arrange to have 256 colors in Tmux inside Gnome terminal so I can use Vim's 256-color scheme?

I found this, I added to the ~/.bashrc, working fine but once I tmux the setting goes off. — Luis D Urraca, May 09 '12 at 02:56
I found help in #tmux channel on irc.freenode.net.
for 256 colors in tmux your 'echo $TERM' needs to return screen-256color and mine was returning screen. So i followed the instruction on this link https://wiki.archlinux.org/index.php/Tmux#Setting_the_correct_term and everything worked. — Luis D Urraca, May 09 '12 at 03:22

Even though OP answered the question in the above comments, I'll add the details here for easy reference. The quick solution is to add the following to your .tmux.conf file:

set -g default-terminal screen-256color

For more detailed info, check out the Tmux page on ArchWiki, or this helpful answer to the same question.

It seems that having active sessions prevents new sessions from honouring the default-terminal option in .tmux.conf as well as passing -2 as a parameter to tmux. Killing all sessions seemed to solve this for me. – Matijs Jun 30 '14 at 13:43
This doesn't work for me. Neither does using xterm instead of screen work. – trusktr Jul 17 '14 at 02:16

There is also the -2 command line option for tmux - c.f. older question
