How is Monet like a honeybee? What color is a whisper? Why is it so hard to find your car in a lamp-lit parking lot?
Color Uncovered features a wide spectrum of cool color-related topics to explore. Learn why friends shouldn’t let men buy bananas. Try your own color experiments on the iPad using simple items you have at home: a CD case, a drop of water, and a piece of paper. Discover how the iPad and other devices create color.
