Color and the Spectrum
Steve Beeson, Arizona State University
What would our world be like if we could not see color? Would it be like our mental image of an old black and white film? Would we even strive to create paintings or fashion? Would we know anything about the structure of the atom? Would we have even evolved into hominids? Doubtless our world and society would be very different from the way we currently perceive them. But what is color and why do things "have" a certain color? Furthermore, are there other manifestations of "light" that we can't see with our eyes? Let's explore the world of light, color, and the electromagnetic spectrum to answer some of our questions.
