Out of the 10 MINI Cooper colors listed on the miniusa.com site, only 8 of them have been in production so far as I know. Velvet Red and Pepper White are soon to be available in the UK but no customer cars have yet been delivered. If I am wrong on this someone will correct me. Out of the 8 colors of Coopers delivered so far in the UK, I have seen only 4 of those in US VPC pictures--Pure Silver, Indi Blue, Chili Red, and Liquid Yellow. I would expect that the other 4 colors would turn up in another shipment, before US MINI dealers open for business in late March, because I think that BRG and Black will be popular US colors.
Out of the 8 Cooper 'S' colors available in the US, only the two exclusive 'S' colors have been delivered so far--Dark Silver and Electric Blue. Whether US dealers will get any other colored 'S' for demos is still unknown to this point.
Hopefully, all these types of questions can be answered, once dealers are open. But until then it is just speculation.
P.S.

Kudos to Utah, Salt Lake City, Park City for its problem free hosting of the 2002 Winter Olympics.
