Abstract
A toy or game piece for producing color includes a housing formed in the shape of a toy; a color reader to read a sample and generate data; a processing device to process the generated data and determine a color of the sample based on the generated data; and a light emitting element to produce light corresponding to the determined color. The light emitting element may include two or more light emitting diodes (LEDs) of different colors. The processing device controls the intensity of each LED to cause the light emitting element to produce the corresponding color that is substantially similar to the determined color.
