Mix-N-Match Light

This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match. Although this is a perception activity, it also demonstrates the difference between mixing colors of light and mixing pigments. Why when mixing pigments does the color darken? How does this differ from mixing colored light? Find out here!
