Newton's Theory of Color states that objects appear to be certain colors because they absorb and reflect different amounts and wavelengths of light. Newton used prisms to prove that white light is actually made up of waves of different colors. This was a radical and controversial idea for the 1660s. At the time, most scientists thought that prisms somehow added color to light.

In 1666 English physicist Isaac Newton bought his first prism in an attempt to disprove Descartes' wave theory of light. Newton claimed that Grimaldi's diffraction was simply a new kind of refraction. He argued that the geometric nature of the laws of reflection and refraction could only be explained if light was made of particles, which he referred to as corpuscles, as waves do not tend to travel in straight lines. After joining the Royal Society of London in 1672, Newton stated that the forty fourth trail in a series of experiments he had conducted earlier that year had proven that light is made of particles and not waves (Newton, 1671/2, pp.3075-3087).

Advocates of the wave theory had previously stated that light waves are made of white light. The spectrum that can be seen through a prism is formed because of corruption within the glass. This means that the more glass the light travels through, the more corrupt it will become. In order to prove that this was false, Newton passed ...more

Newton used two prisms to prove that the color was in the light, not in the prism. He placed the first prism in a beam of sunlight and projected the rainbow spectrum - red/orange/yellow/green/blue/indigo/violet - on a wall 22 feet away. To further prove that those colors were components of the light, he inserted another prism into the path of the projected spectrum and reconstituted the beam of light so that it shone white again.
