• Each band or level, being a particular manifestation of the spectrum, is what it is only by virtue of the other bands. The color blue is no less beautiful because it exists along side the other colors of a rainbow, and "blueness" itself depends upon the existence of the other colors, for if there were no color but blue, we would never be able to see it.
