The world is a colorful place, and human eyes have evolved to take it in – from vermillion red to bright tangerine to cobalt blue. But when we do, are you and I seeing the same thing?  Find out why color perception is a trick of the brain, and why you and I may not see the same shade of green. Or blue. Or red. Also, platypuses and the growing club of fluorescent mammals, and the first new blue pigment in more than two centuries.   Guests: Paula Anich – Associate Professor of Natural Resources, Northland College Michaela Carlson – Assistant Professor of Chemistry, Northland College Rob DeSalle – Curator at the American Museum of Natural History, and co-author of “A Natural History of Color: the Science Behind What We See and How We See It” Mas Subramanian – Professor of Materials Science at Oregon State University   Learn more about your ad choices.
