Light is a form of energy that takes the shape of magnetic or electrical waves, and these waves are reflected off of or emitted from matter. According to Sir Isaac Newton's theory of light and color, since these waves of light have different frequencies and wavelengths, once reflected off of or emitted from matter, these waves appear as colors. According to the Young-Helmholtz theory, also called the trichromatic theory, we are able to see color because the retinas of our eyes are formed with three types of cones that are sensitive to the wavelengths of the three colors; red, green and blue. Therefore, the difference between light and color is that light is energy made up of wavelengths, whereas colors are the various wavelengths our eyes are sensitive to and can see once the light is reflected from or emitted from matter

B they tend to promote because training and getting people ready takes a lot and they want to keep them there as long as possible instead of paying to retrain people all the time
