Oh, I see what you mean.

This is why the second paren always had a % before it:

writefln('%Cred((this is in color)%)');

Is this OK?  I know that escaping is still involved, but the text itself 
does not need escaping: only the special closing element does.

I like this constraint because it means that the only character you ever 
have to escape in your normal text is %, which you write by using %% 
instead.
