If you have to specify "tmux -2" then something is wrong with your environment. That says your terminal supports 256 colors but isn't declaring it correctly.
With OS X 10.7+ and the Apple Terminal, configure "xterm-256color" support. This is done in Preferences -> Settings -> Advanced -> Declare Terminal As. I'm not sure about prior versions. With iTerm2 set this in Preferences -> Profiles -> (Default or another profile) -> Terminal -> Report Terminal Type. This correctly declares the environment variable $TERM as "xterm-256color". When tmux sees this it will automatically enable 256 color support, no "-2" needed. Programs running inside of tmux need the "screen-256color" setting you mentioned to see 256 color support. If you are on an older Linux or UNIX system it may not have the xterm/screen-256color terminfo data. In that case you can grab the configuration file with: > infocmp >> terminfo.src then add the settings with: > tic terminfo.src If you do the first command from inside tmux you'll get the screen-256color settings, otherwise you'll get xterm-256color. Here's a shell color test script from the vimwiki folks you might find helpful to verify 256 color support. -Adrian On Oct 30, 2012, at 6:38 PM, John Schmitt <marmalo...@gmail.com> wrote: > On Tue, Oct 30, 2012 at 08:15:50PM -0500, Mark Volkmann wrote: >> Just finished reading the excellent book "tmux: Productive Mouse-Free >> Development"!
