  • Text color codes:
 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white
  • Background color codes:
 40=black 41=red 42=green 43=yellow 44=blue 45=magenta 46=cyan 47=white

Bash shell colour codes

This following code echoes a bunch of colour codes to the terminal to demonstrate what's available. Each line is the colour code of one forground colour, out of 17 (default + 16 escapes), followed by a test use of that colour on all nine background colours (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";
