How do I set the colour of brackets/braces/parentheses in Emacs?

Question

I'd like to specify the colour of {}, () and [] in a custom colour theme. Is this possible?

Update: Here's the source. Please note the in-development status of this theme; it is unsafe for use both at the workplace and around the home.

Try:

(font-lock-add-keywords nil '(("\\([\{\}\\[\]\(\)]+\\)" 1 font-lock-keyword-face prepend)))

For parent match only:

Evaluate the following expression or put it into your .emacs:

(custom-set-faces
 '(show-paren-match ((t (:background "blue"))))
 '(show-paren-mismatch ((((class color)) (:background "red" :foreground "white")))))
