definitely don't do brown
brown clashes with black. It only looks good on classic bikes with all silver components.
I've got a similar blue bike and I went green like Subaru rally colours. That would look good on yours. So would pink, red, purple, orange or yellow.
Black does look good. Your frame colour is enough. White would look good too, to match the decals, but it's a bit harder to pull off and can be annoying to keep clean.
oh yeah and move your light to the rack. That might involve zip ties for the bracket. Or get one which can bolt on there.
