I'm trying to set something to gray, but can't figure out how. The only bit of info in the man page about colors I can find is:

message-bg colour
  Set status line message background colour, where colour is one of:
  black, red, green, yellow, blue, magenta, cyan, white, colour0 to
  colour255 from the 256-colour palette, or default.

I also found a blog post which iterates through colors, but I can't quite grok it, and don't want to sit at the terminal all day guessing color numbers until one works.

You can get a list with this bash script:

for i in {0..255} ; do
    printf "\x1b[38;5;${i}mcolour${i}\n"
done

Then use colourxxx with tmux.

use $ reset to get your prompt color back :> –  lkraav Feb 14 '12 at 10:26
    
perhaps you need three digit colours? This script outputs like color12 but that is not accepted by tmux as a valid colour. –  artfulrobot Jan 11 '13 at 11:49

My tmux (1.6) accepts even colors like colour12 (mind the "u"). –  cYrus Jan 11 '13 at 12:28

This answer is still helpful! Helped me pick the colors I wanted. –  asfallows Oct 18 '13 at 20:48

In Subversion (what will be tmux 1.5) you can also use #abcdef hex-style colours which are mapped to the nearest 256 colour palette entry. You need quotes as it's treated as a string, whereas regular color names are treated as named constants. Also note that 3-letter shorthand (#f00) is invalid.

Example:

set pane-active-border-bg red # no quotes for name
set pane-active-border-bg "#ff0000" # quotes for rgb

Can you? I can't see how to... –  Eric Apr 23 '12 at 18:18

set-option message-bg "#abcdef"; the quotes are necessary. –  chepner May 1 '12 at 20:05

I've been using the xterm-color-table.vim script. Any 256 color terminal color table will work.

tmux through 1.9 only supports British spelling of 256 color palette, i.e.

"colour121"

as opposed to the American spelling

"color121"

Looks like this will be fixed soon, http://sourceforge.net/mailarchive/message.php?msg_id=31049758
