^^^^ The only from the factory orange bar I know of, the Easton EC90 SLX all carbon road bar. It's not quite as red as it looks in the pic, it's a very nice reddish orange. They weigh less than a fart and cost more than a divorce. Probably not what you want, though.
You can get bars powder coated anywhere, I'd guess about $20-30. Very cheap part to do, no stripping, no threads, just a little masking in the clamp area.
