Controllers were made in a different factory. That said, orange controllers were made for the Xbox Live team, of which I own one and are rare in themselves. Both were considered for a potential Xbox Live set, but it obviously wasn't made. The Halo print is there because it probably came from the same place making it. When its a sample, it doesnt really matter.
Be sure to check my earlier post too, I added bits about other colors.
Here is my Xbox Live controller. The colors are slightly different, because again, different factories and they weren't color matched like you would see if they were retail kits.
