This interactive simulation allows users to explore how people view colors. In the first view, users control three monochromatic lights of varied intensity to produce multiple colors.  The second view allows users to filter white light and monochromatic light and study how the filter determines what colors pass through to the eyes. The color of both the light and the filter can be controlled by the user.

This simulation is part of a large and growing collection. It has been designed using principles from physics education research and refined based on student interviews.

Please note that this resource requires Java.
