More fine grained syntax highlighting in Emacs/AUCTeX

I'm using Emacs with AUCTeX to do all my LaTeX. When it comes to syntax highlighting it seems that all mathematics is by default just orange. Do you know of a mode or package that adds some more fine grained syntax highlighting? For example all commands (\foo), matching braces, sub- and superscripts, etc. should get a different color.

I have the same problem and couldn't find the proper answer. However at the moment I am using highlight-regexp in my LaTeX-mode to highlight syntax in math mode and everywhere else :). Also you could use default font-lock

(add-hook 'TeX-mode-hook
(lambda ()

Very nice addition. Just added it to my .emacs. –  jon Aug 16 '12 at 14:07
