So that suggests you read my previous comments, but didn't see fit to
look at all of them or respond.

*How* are you taking colorblindness into account?  Which type of
colorblindness have you tried to address.  Certainly not red/green
which, I believe, is the most common form.

But, more to the point:

- You do not know that your output is going to a terminal at all, much
  less one that understands these escape sequences.

- You do not know whether that terminal, if it exists, is in dark mode
  or not.

- You don't check NO_COLOR to see whether the user has explicitly asked
  to not have colorized output.

This is a simple script meant to check dependencies, it really does not
need this kind of silliness.  Surely there is something more useful you
could work on?
