I just thought of something - I love bright colors, but I have (thus far) refrained from buying/wearing apparel that clashes with my bike(s). For instance, I like bright orange, but my bike is primarily red and gray, so no bright orange jersey or jacket for me.

Then again, I still have the Domane in the basement, waiting to be sold, and that's a blue/gray that would look good with orange... Now that would be some cycling vanity - buying/keeping a bike so that you could wear complementary colors that you fancy.
