I gave it a try on a landing page once and it shit the bed though when put up against other combinations. I've seen red on black do well for adult traffic myself, and you'll notice the combination in use on a lot of landing pages. Red being an action color, it supposedly represents heat and passion, yadda yadda.

I did all the reading I could on the subject a while back now, but when I went looking for more detailed reading on the subject of color theory and advertising I couldn't seem to turn shit up for decent resources. It's all theory, but it definitely plays a roll. Best I can say, is split test different color combos against your traffic and see what plays out for you over time. Different combos seem to work well for different things. Ever notice that a vast majority of female weightloss pages are that same old green/purple combo? Depends what type of emotion you're attempting to trigger.
