Reading through some of the subsequent responses, I want to make it clear that I was not endorsing common perceptions engendered by these terms, just reporting them (nor was I trying to define them). I personally have a low tolerance for both excessive or obvious warmth *and* analytical-ness, and consider 'neutrality', to the extent that we can obtain or be sure about such a thing, to be a virture.
I also think that the definitions offered above only touch on some of the aspects involved in generating these perceptions - the question actually goes beyond just tonal balance to me - but I'm going to refrain from expounding further since it's all very subjective anyway. But for the record, I find Rockvirgo's explanation to cover the whole gestalt more satisfactorily than a technical exegesis likely would.
