I have, a long time ago. I got something that looked really cool, to me. It did have a greenish-bluish-silvery-ish color to it. It almost looked metallic. Pretty, but not as contrasty as I usually like. It was a look all it's own. I didn't keep doing it though. In fact, I think I threw all the color paper away.
edited to add; if you can get into photo.net you might still be able to see this. i can see it. i must have scanned it in grayscale because you can't see the color of it, but this is the b&w negative printed on color paper. http://photo.net/black-and-white-pho...g-forum/004a6o
