No one has ever seen a subatomic particle. They don't have a "color," or an "appearance," or a "surface." In fact subatomic particles aren't really particles at all, but more like waves of probability. They're completely outside our experience, so to speak of them at all we create metaphors. But then we find paradoxes in the metaphors and, forgetting that the map is not the territory, we proclaim that the paradox exists in nature.
