Magenta is a deep purplish red, and cyan (pro- nounced SIGH-an) is a greenish blue. Both colors are used in photography and color printing. Mixing colored light does not produce the same outcome as mixing colored pigments. Children can compare the results of combining colored lights with what happens when they mix colored paints in the art area. In this experiment, children use flashlights to pro- duce colored light. The flashlights are modified in one of three ways: (1) the lighted end is covered with red, blue, or green cellophane; (2) the lighted end is cov- ered with clear plastic that has been colored with red, blue, or green permanent marker; or (3) red, blue, COPYRIGHTED MATERIAL
