The color matcher is a program written to allow students to explore the concepts of three dimensional colorspace. The game is played with with one to three players with each player controlling one or more colors.
The object of the game is to match a target color displayed on the screen. If there is more than one person, players have to coordinate with each other to get the proper match. Players receive a score based on how "close" their color matches the target.
Here's a picture of the Color Matcher user interface.
The color matcher was written as part of the METIP project and was supported in part by the National Science Foundation under grant number MDR-9155709.
