Personally, it would still be Forest Green for me. I'd like to see red or blue as well - the blue XSR 900 looks good. It would be interesting to know how many of each colour Yamaha have sold. Black rad is a definite improvement. Silver wheels would look good on all colours IMHO. It's a pity the Yamaha tank logo doesn't stand out on the black bike - perhaps white or silver lettering would have been better?
The black rad for all colors is definitely a correction of a stupid beginner mistake. It is also a sign that the yamaha designers have ears on the Internet and take corrective action if necessary, which is a very good thing. For many other brands this is not the case.
