Hi, for what its worth, i have created a nice little function that shows the many different colors that can be used in the terminal and its available as part of a little centos7 base installation setup i created a while back.

The function code as of today is as follows:

# Displays useful sets of terminal colors based on param input either set by default aliases or user-defined... When looking
# for a color theme for a project, bash-colors-random has prooven to effortlessly throw some decent color combination.
function bash-colors() {
  local SEQNUM=${1:-4}; [[ "$SEQNUM" -eq "0" ]] && SEQNUM=4;
  tput rmam;
  seq -ws ' ' 0 ${SEQNUM} 256 | \xargs -n1 bash -c \
  'echo -ne "\033[1;48;5;${0}m \\\033[48;5;${0}m \033[0m"; \
  echo -ne "\033[1;7;38;5;${0}m\\\033[7;38;5;${0}m \033[0m"; \
  echo -ne " \033[1;38;5;${0}m\\\033[1;38;5;${0}m\033[0m"; \
  echo -ne " \033[38;5;${0}m\\\033[38;5;${0}m\033[0m"; \
  echo -ne " \033[2;38;5;${0}m\\\033[2;38;5;${0}m\033[0m"; \
  echo -ne " \033[3;38;5;${0}m\\\033[3;38;5;${0}m\033[0m"; \
  echo -ne " \033[4;38;5;${0}m\\\033[4;38;5;${0}m\033[0m"; \
  echo -ne " \033[9;38;5;${0}m\\\033[9;38;5;${0}m\033[0m"; \
  echo -ne " \033[4;9;38;5;${0}m\\\033[4;9;38;5;${0}m\033[0m"; \
  echo -e " \033[1;3;4;9;38;5;${0}m\\\033[1;3;4;9;38;5;${0}m\033[0m"';
  tput smam;
}
alias bash-colors-full='bash-colors 1';
alias bash-colors-minimal='bash-colors 8';
alias bash-colors-less='bash-colors 2';
alias bash-colors-random='bash-colors $(shuf -n1 -i 1-64)';

and is available here: https://github.com/mathieu-aubin/c7repos/blob/master/functions/bash-colors

In order to add this function to your set of 'tools' you can either create a separate .bash_functions file that you later source from your main rc file or you can use this code:

curl -sLk https://github.com/mathieu-aubin/c7repos/raw/master/functions/bash-colors >> ~/.bashrc

Then source the ~/.bashrc file using source ~/.bashrc or opening another terminal. You will then have 'bash-colors' (and its derivates) available for your pleasure.

Here's a little demo (thanks to asciinema - click on the pic to view)

The i have removed the \033[ from the output in the demo function to shorten the output the function remains the same.

Thanks

Thanks @mathieu-aubin ... thats a great little utility.

I have created that as a gist, with some bashism tweaks
