Well, now that I got the complaining out of the way, gonna do some speculating.
Reshiram has a very "ghostly" feel to it, from the wispy hair/fur/tail, and the feathery/angel like wing. Suffice to say that I think Reshiram will be in charge of the afterworld/spirit. Ghost/Flying: bank on it. Drifblim: here comes the competition! (Not) Black has also been traditionally a color of mourning (I think), and could be associated with the void, underworld...etc etc.
Zekrom, like other has mentioned, has a very metallic, artificial look to it. Its wings, unlike that of Reshiram, are rigid, angular, and while Reshiram is fur like, Zekrom is streamlined and compartmentalized. Not to mention the metallic, engine like tails. Zekrom then will be a Pokemon resembling the artificial then? Steel/Dark, based on its coloring? White can be interpreted as steel-like, artificial cleanliness, if you want to stretch it...
It's not uncommon to find the theme of Spirit vs. Technology in Japanese art/anime, with Princess Mononoke coming into mind. I wouldn't be surprised if B/W is based on this then.
