====== 256 Colors ======
Once upon a time, having a colored terminal displaying whole eight different
colors was subject to the geeks amongst all the terminal users. Nowadays,
this is nothing special anymore. Consequently, one has to go further: 256
colours!
===== rxvt-unicode =====
Compile with support for 256 colours (''--enable-256-color''), then make sure
''$TERM'' is set correctly:
URxvt.termName: rxvt-256color
===== Bash / Zsh =====
Clone dircolors-solarized.git:
# git clone https://github.com/seebi/dircolors-solarized.git
Copy one of the //dircolors.*// files to //~/.dir_colors// and add the
following to the shell's init script (if not already provided by the
distribution's global one:
eval $(dircolors -b ~/.dir_colors)
===== Vim =====
Just add the following to //~/.vimrc//:
set t_Co=256
Optionally search for a nice colorscheme supporting 256 colors (default was
fine for me).
===== Screen =====
This depends on the value of ''$TERM'' at the time ''screen'' is started -
''rxvt-256color'' is fine. Or maybe not? In doubt, one may override it:
term xterm-256color
===== Mutt =====
Compile with slang support (''--with-slang''). Maybe not necessary, but
certainly useful.
Mutt's colors are subject to customisation anyway, but here's a nice sample:

#Display the color
echo -en "\e[${fgbg};5;${color}m ${color}\t\e[0m"

This one is also nice, found on
[[https://gist.github.com/eliranmal/b373abbe1c21e991b394bdffb0c8a6cf|Github]] and
customized to get default parameter from tput output:
#!/bin/bash
ncolors=${1:-$(tput colors)}
echo "showing $ncolors ansi colors:"
for ((n = 0; n < $ncolors; n++)); do
printf " [$n] $(tput setaf $n)"
printf "wMwMwMwMwMwMwMwMwMwMwMwMwMwMwMwMwMwMwMwMwMwMw"
printf "$(tput sgr0)\n"
done
