OVER THE RAINBOW
This is one of my favorite books of experiments for beginners. It is written by Barbara Taylor and was published by Random House in 1992 for the Step into Science Series. It is out of print but can be found used.
An introduction to the science of color and light using simple experiments to show how people and animals see colors, how to make colors, and how to use them in painting, printing, and other projects.
