Using the grc app on Linux (Debian / Ubuntu) you can easily colorize your shell environment. This will work for Bash or ZShell.

Colorization of cli application output:
apt install grc
nmap -v -sS


This makes output of cli commands easier to read.

Set the above nmap command to always colorize by editing your .bashrc:
nano .bashrc
alias nmap="grc nmap"

You can do the same thing for other commands from the shell or installed apps.
