Abstract: The toy for teaching colors is a series of three translucent discs or panels, with each disc or panel having a different additive or subtractive primary color. Each disc or panel includes a relatively thick rim adapted and configured to facilitate handling the devices, particularly by small children. The discs or panels may be provided in a variety of different regular and irregular shapes, as desired. Complementary engagement between individual units, e.g., mating depressions and protrusions, etc., may be provided. The toy is particularly valuable for teaching very young children the effects of combining different additive and subtractive colors to arrive at another color, and may have additional value in teaching that color is a superficial attribute of objects as well as people, and, thus, that people should not be judged by their external appearance or color.
