Newtons Famous Prismatic Dispersion Experiments

Newton allowed a small beam of sunlight (white, or achromatic, light) to pass through a prism in a darkened room. The light that emerged was no longer white 

Sunlight consists of a mixture of all the colors observed in the prismatic spectrum (a word that Newton coined). 

The prism is capable of dispersing the white light into its constituent colors. (Therefore, color was a property of the light not of the prism).
