FWIW, I haven't seen BMW specifically offer a pre-painted Euro bumper. You can go through multiple vendors here to do it, but I would advise against it. Not bashing their work, as they all do great work, but from what I have read, there will be slight color differences.
It's best to get the piece primed, take it to a reputable body shop, and have them color match it. This way, you'll get a perfect match with no issues.
