The white color

It is typical for the white light that it contains all the other colors in a perfect proportion - their quantities are strictly determined. The white represents the absolute reflection of the light - the same as the light which came to the surface. White colored substances do not absorb any rays from the spectrum, they don't miss any rays, they are complete and perfect. Red things for example needs all the rays but red ones and that's why the red are those they reflect and we are seeing them after this reflection. All the other part of the spectrum is absorbed because the red substances need it. However as white don't need any rays and can reflect everything, everything is forwarded and don't keep for them anything. Probably at the end all things will become white.
