yes, its normal
when I first read your post I was going to say that it is impossible to tell from your pic for certain if the bulb is new or not, but just that if you bought it from a reputable source it is probably new.......
Then for kicks....I went and looked at 8 others that I have running, a few others that are retired, and three brand new ones and came to the conclusion that if you see orange.......its new.
As I said above....kinda funny with the number of radiums I use I didnt know that already without looking.
