Yes I do dream in color, but then I can also lucid dream. (For finding out if you're dreaming or not, press your fist to the wall in your dream, if it goes through...you're dreaming.)

The most wild "color" dreams I had were while on lunesta--they don't advertise with the green fluorescent butterfly for nothing! ALL the elements within the dream were that way...alas it also caused night terrors so I quit taking it...

so now my dreams are regular color.
