+1 for this. It's basically impossible to get emacs colors to work correctly in the terminal.
But don't complain, better submit a patch. Or help ironing out the one linked above, it's unfinished.
If I hadn't then why would I say so?
I just think the graphical Emacs provides the most comfortable environment. It displays images (and thus also PDF files or a graphical browser widget), doesn't swallow the Alt key by default, has prettier colours, and you still get to edit remote files with TRAMP.
This doesn't mean that Emacs in a terminal should not be improved. I sometimes use it when I ssh into my workstation from a machine that doesn't have Emacs installed.
But what use is there to complain to them? None of them sound to be anywhere close to the Emacs development.
