Date May 7, 1987.In a display device for illustrating color mixtures, one color each in various intensities is printed on various transparent color wheels. The color wheels are concentric with respect to one another and are individually rotatable. Along their circumference, they are each provided with a tab for adjustment. The color imprint on a color wheel is provided in gradations of increasing or decreasing intensity along the outer circumference of the color wheel. The color wheels are covered with a covering wheel of non-transparent material, which has a recess for observation of the color mixture obtained by adjusting the color wheels. A scale which is associated with the rotational position of the color wheels is disposed on the covering wheel.
