Right now it does

(5): white-noise      - White uniform noise
(6): pink-noise       - Pink noise

According to http://en.wikipedia.org/wiki/Colors_of_noise
red is a synonym to pink or brownian noise. Anyway, I filed
https://bugzilla.gnome.org/show_bug.cgi?id=649969
which would be an easy one for someone who would like to start
contributing to gstreamer (hint hint).
