Well I don't know the point of this (I guess who cares if there's one).
But what if you took colour out of art (not just anime art)?
95% of the art would be gone at least.
What if you took the letter e out of the English language, or vowels?
Obviously, it is too some extent foolish to even ask, these aren't the greatest analogies, but they analize the pointlessness of such a question.
But if you enjoy pointlessness (believe me I do as much as the next guy), then go right on ahead.
Don't fool yourselves that its anything else though (heck this might apply to more than we think

)
