Baby Claudia in a sea of pink
“Visible light” corresponds to a wavelength of 400 – 700 nanometers or 10-07 meters. The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. You’ll notice that the color pink doesn’t appear anywhere on that list.
Recently, there has been debate as to whether or not the color pink actually even exists. Some claim that it isn’t a color because it doesn’t appear on the ROYGBIV electromagnetic spectrum. Others counter that argument, explaining that just because our brain “creates” the color pink by combining two opposite ends of the spectrum–red and violet–does not preclude its existence; after all, any color, according to biologist Timothy H. Goldsmith, is simply “a sensation that arises within the brain.”
