Yes if you look at all the insides of the ANH helmets seen previously they look pink in colour from the overspray of the red primer and white paint.
If you look at the good resolution pictures that were posted by Keith of the 'Stop that Ship' and 'Move Along' you can clearly see red primer where the paint has flaked off and where the ear caps were removed.
This is one of Keiths' pics - Keith if you want it removed just say.
Here is the inside of the first TE helmet
I also think on the Set for Stun helmet the red mark on the top is the white scuffed off leaving a red primer mark.
