About This Lesson
Colored lenses change our perception of the world’s colors by acting like filters: they absorb all colors of light except for whatever color the lenses are. When we look through colored lenses, we’re actually seeing what the world would look like with some of the primary colors of light removed. Explore this phenomenon by making a cool pair of color-filtering glasses using colored cellophane or light filters. Then conduct an experiment to determine which colors you are no longer able to see when you wear your color filtering glasses.
