Hi
Okay, I can see the problem.
$ TERM=screen-256color tput setaf 15|cat -v
^[[97m
$ TERM=xterm-256color tput setaf 15|cat -v
^[[38;5;15
It appears screen-256color converts colours 8-15 into 90-97 which are an
extension designed to allow bright colours without the bold attribute (bold
font).
Looking briefly at xterm-256color in terminfo.src I can't see why it doesn't do
the same but I don't have time or inclination to dig into it right now.
I'm not certain why it does this because in 256 colour mode, colours 8-15 are
supposed to be the bright ANSI colours anyway, compare:
$ echo -e \\033[93mabc\\033[38\;5\;11mdef\\033[33m\\033[1mxyz
This appears to be yet another terminal capability without a terminfo flag
allowing it to be detected so tmux can't make use of it explicitly (ie pass it
through if it is supported). However, converting it into colours 8-15 (which
should then be converted into 3x+bold for non-256-colour terminals) should
hopefully do the trick.
Please try this:
