Bash color coding

I need your help again.

In my job we often need to log in to a customer system and verify a thing or two. I Automated the General Health-check we need to perform with every login, with the script below, and it works well.

It needs to be in one-liner form because we can't upload it as a file on to the machine.

However, I decided to color code the output to make it even nicer, but color color doesn't apply for the text inside the "for" loop.

I have some very basic understanding of quotes as follow:
Double quotes("these") allow special characters to be noticed/obeyed.
Single quotes('these') make the interpreting shell ignore all special characters

This lead me to think that issue comes from the single quotes('these') withing which I nested the "if" statement containing the "echo -e" commands. I have tried with "printf", but color coding still doesn't work.

If I remove/replace the single quotes, the script doesn't work. After "ssh module-$i" is executed, script terminates.
I tried replacing the single quotes('these') with double parenthesis"((these))", or back single quotes(`these`) with no success - still doesn't work.

Any idea how I can rewrite the code so it works?

Here comes the code:
