Pink is the New Green

Michael Loik, of the Loik Laboratory in the Environmental Studies Department at the University of California, Santa Cruz explains why the choice of pink: “That is because of the dye that was selected to allow the red wavelengths of sunlight to be able to pass through. Colors that are not absorbed by the dye are reflected or transmitted. In this case, the dye absorbs green and some of the blue. The blue that is not absorbed, as well as the red wavelengths of sunlight, are transmitted or reflected (red + some blue = magenta).”
