Looks like you're right. Found this press release at BMW:

Also it sort of explains my other question. Sunset Orange is a reference to the mid 70's colors so my thoughts of the inside orange beeing related to the 2002 wasn't completely off. BMW states in their press release:
"Furthermore, with the available range of body colours, the BMW 3 Series demonstrates yet again a sense of tradition. New in the range is Sunset Orange – a contemporary interpretation of the colour which was popular in the 1970s and available for the first generation of the BMW 3 Series initially as Inca Orange and later as Phoenix Orange."
Thanks :-)
