In the exhibit, eleven dots of light surround a central dot. The dots, all created by a different mixture of red and green light, vary in hue from green to orange. Visitors are asked to state which of the surrounding dots best matches the central dot. Since everyone perceives color differently some people may say two colors match and you may disagree.
