Definition of colors ,classification of colors

Answer 1

This color classification of Newton is relevant even today. The color spectrum he had arrived at is akin to the color spectrum of a rainbow. The light is radiant but a visible energy of electromagnetic wave motion, which moves through space at an incredible speed of 186,000 miles per second. Like X-rays, or, radio signals it is transmitted through electric vibrations and magnetic fields, though, of course, at different frequencies. It moves in waves and the measure for lights wavelength is Angstrom Units (AU).sensation produced on eye by rays of light when resolved as by prism into different wavelengths; one, or any mixture, of the constituents into which light can be separated as in a spectrum or rainbow.
