I like cameras that stand out from the crowd, and while I reckon the white version of Pentax K-m was a stretch for most people, I think it's far more agreeable in olive green (above).
Pentax has also announced a titanium color (I would say chrome) K20D, pictured below. That's the good news, the bad is that both appear to be limited to a 1000 units in all and are for domestic consumption (i.e. to be sold in Japan) only. For more pictures and info (in Japanese only) please visit here.
