In the second part we will learn about hue, saturation, and luminosity. In the first part of this laboratory we will look at how televisions and monitors produce the colors of the rainbow. In this three part laboratory we will explore the colors of light and systems of organizing colors. What are the primary colors of light? What are the secondary colors of light?
