I've been using paredit with my clojure for a while now and I really love it. But how do I get those multi coloured matched brackets? I've seen them on others screenshots too, but I don't know which mode enables them in my emacs.

Also, I've found with paredit that it keeps the brackets balanced until I paste in a segment of lisp with unmatched brackets. Then it gets in a bind and I need to either disable paredit to manually fix it, or go into overwrite mode to fix it. Is there any graceful way to deal with bad bracket-unmatched code pasting in paredit?
