Color, like beauty, is intrinsic. IMO The usual reductionist thinking is that color is assigned by our minds according to the frequency of the light sensed. Light does not contain or carry the property or value of color but rather has frequency, wavelength or energy level that we perceive and as the value of color to it. I, myself have long thought this and thought the same about sound. I was wrong. Having thought about this for some time I have come to the conclusion that color, sound and beauty are intrinsic and perceived as those values rather than assigned those values by our minds. Following are the reasons that I have changed my position and it has to do with information more than perception. Light, photons are generated, emitted by bodies, in quantum. The energy level of the quantum of light is determined by the energy level of the emitting body. This energy leveldetermines the frequency or wavelength of the light, photon, quantum. This wave length is information about the radiating body that we can and do perceive as color. If the light is reflected off of another body, the light then is altered. Its characteristic wavelength and intensity is changed by the reflecting body unless it is a perfect reflector or mirror. This is information about the reflecting body. The medium through which the light travels may also change its characteristics and this is information about the medium also. With our eyes and instruments we can detect these characteristics and deduce which characteristics are due to which process or body. Light (and sound) of different frequencies or wavelenghts or energy levels have different properties of reflection, penetration etc. All of this is a function of its wavelength which is intrinsic to the light. We call these different characteristics color. Color is generated or radiated outside of us and comes to us with this information we call colors as an intrinsic characteristic. We may assign the name of the color and we may all perceive each color differently but it is still a perception of a characteristic of the light entering our eyes. Life is an opportunist. It takes advantage of whatever is at hand. It uses it's environment any and every way it can. Vertually every form of life on earth uses and responds to light in some way. Sight is a sense that was developed by life to gather information about its surroundings using light. Life did not invent light nor did it invent color but evolved to use light and its characteristic colors to gather information about its environment. Again, we, life, do not invent or assign color but percieve color as an intrinsic characteristic of the light we sense and this color is information contained or carried by that light that is external to us. I welcome any and all thoughts, ideas, and/or arguments for or against.
