I like having a red bar for tmux running as root and a blue one for running it as a normal user, e.g. for root:

    set -g status-style "bg=red"

I also like to have the bar on top and the status centered:

    set -g status-justify absolute-centre
    set -g status-position top

I change the color of the bar in every server I've set it up so I know absolutely where I am.

Aren't you going to run out of colors to pick?

		My approach is to color ssh sessions to prod servers red, less dangerous servers orange, my own non shared computers blue.

Do you use this when running tmux remotely?

(I only run it in my own machines so it never runs as root anyway)
