You know what's really cool? Black is a relative colour. So is white.

So if we took Obama into a pitch dark room and then focused a beam of highly collimated light upon his hand he'd appear white! But then if we brought in a second person who is white and shone a light on his hand too, Obama's hand would suddenly appear very dark black! Now if we took the white person out and instead used someone with very dark skin, Obama's hand would appear lilly white again!

So to answer your question: Obama is both black and white at the same time. He is black enough, and white enough, and brown enough in the right lighting conditions! That is what you meant, right?

Unfortunately, we cannot actually use Barack Obama to prove that he is black and brown at once. His bioluminescent signaling would provide ambient light giving context to the colours and annulling the test. Although some whackos would have you believe that the light emitted by barack obama is the light of holy righteousness, I scoff at such unscientific theories and instead believe he has a complex systems of photophores in his skin that he uses to communicate emotional information much like a squid.

But if he ever turns bright red, RUN! You'll thank me after you escape the feeding frenzy when he gorges himself on honkey brains and goes on the hunt for white women to impale and implant his spermatophores in her torso, so she can store the sperm for later use..
