"Color," said Isaac Newton, "belongs to the mind and not the object." Current research continues to prove Newton's observation; the eyes are go-betweens in a mental process that depends upon pigment and light. Museum visitors have the opportunity to use a prism to separate light into a spectrum of color,

just as Newton did nearly three centuries ago. Other displays challenge visitors' sense of color perception, and explore the phenomenon of afterimages, the result of overstimulation of the eyes.
