Maybe since grep's output goes to a pipe and not to the terminal it decides to ignore --color. That's the behavior I see on my Ubunutu. Try "--color=always" when you pipe egrep's output, it helped in on my desktop. 2.

You want to mark 'FINDME' but also find every line?
grep --color '^\|FINDME'
Or:
egrep --color '^|FINDME'

Yes. The key line is:
<<<
$l =~ s/($re)/colored($1, $c)/eg;
>>>
$re is a variable containing a regular expression. s/($re)/EXPR()/eg matches
all occurences of $re (while capturing it as $1) and replaces them with
EXPR(). The expression in our case is:
<<<
colored($1, $c)
>>>
It and returns a string that represents $1 coloured using the colour $c.
As you should note, I assign $re and $c previously here:
<<<
my $re = $pat->{pat};
my $c = $pat->{color};
>>>

Uhh, forgot about that part (I use "grep -color" and it was good for
my needs) but I DID forward you to "man grep" didn't I?
maybe one of the "*-context" options (look for "Context Line Control"
in the manual) help you get what you are after.

That would actually be great and is exactly the kind of solution I'm
searching for. The only problem with the grep --color apporoach is
that It would only show me the lines that contain the search term. I
want to see the whole scrolling log and highlight what interested me.

Following on Moish's first idea you might want to take a look at

vt100 escape codes based a pattern.

Hmmm, well no. I mean more as a tool I would use for debugging during

tail -F /var/log/MyApp/DCN.log | SuperSyntaxHighlighter
-SearchForWord="^regexOrSomething" -SearchForWordColor="#FF"
