Quoting Stephane Wirtel (ste...@be...):

This is not specific to framebuffers. See 

man setterm

or you can send ansi escape codes to your console. You cand find some
info in the Bash-Prompt-HOWTO (that can be found in the standard
locations - probably you have it somewhere). The howto includes this
nifty script for testing all possible colour combinations:

--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--

#!/bin/bash
#
#   This file echoes a bunch of color codes to the
#   terminal to demonstrate what's available.  Each
#   line is the color code of one foreground color,
#   out of 17 (default + 16 escapes), followed by a
#   test use of that color on all nine background
#   colors (default + 8 escapes).
#

T='gYw'   # The test text

echo -e "\n                 40m     41m     42m     43m\
     44m     45m     46m     47m";

for FGs in '    m' '   1m' '  30m' '1;30m' '  31m' '1;31m' '  32m' \
           '1;32m' '  33m' '1;33m' '  34m' '1;34m' '  35m' '1;35m' \
           '  36m' '1;36m' '  37m' '1;37m';
  do FG=${FGs// /}
  echo -en " $FGs \033[$FG  $T  "
  for BG in 40m 41m 42m 43m 44m 45m 46m 47m;
    do echo -en "$EINS \033[$FG\033[$BG  $T  \033[0m";
  done
  echo;
done
echo

--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--

It is probably best for you to include the background change escape
sequence in your shell prompt, so your preferred colour is re-set each
time the prompt is displayed (programs like mc and ls (colorized)
change the setting). 

Hope it helps.
