Does grass look green when it’s dark outside? Can you tell what color your sheets are when the lights are out? No! We need light in order to see colors. We call normal, everyday light from the sun, ceiling lights, lamps and flashlights “white light”. White light is made up of all the colors of the rainbow. If we shine white light through a special instrument called a PRISM, the prism will separate white light into all the different colors of the rainbow.
