echo -e "${CC[15]}This text is black on bright green background."
I usually just use with a function:
# setup_colors - Adds colors to array CC for global use
# 30 - Black, 31 - Red, 32 - Green, 33 - Yellow, 34 - Blue, 35 - Magenta, 36 - Blue/Green, 37 - White, 30/42 - Black on Green '30\;42'
function setup_colors(){ declare -ax CC; for i in `seq 0 7`;do ii=$(($i+7));CC[$i]="\033[1;3${i}m";CC[$ii]="\033[0;3${i}m";done;CC[15]="\033[30;42m"; export R='\033[0;00m';export X="\033[1;37m"; };
export -f setup_colors
CC[15] has a background of bright green which is why it is separate. R resets everything, and X is my default font of bright white.
CC[15]="\033[30;42m"; R=$'\033[0;00m'; X=$'\033[1;37m'
Those are just my favorite colors that I often use in my scripts. You can test which colors by running
for i in $(seq 0 $((${#CC[@]} - 1))); do echo -e "${CC[$i]}[$i]\n$R"; done
