Display device for illustrating color mixtures
First Claim
1. A display device for illustrating color mixtures, comprising:
- a plurality of concentrically arranged, transparent color wheels each having a color printed thereon of varying gradation, and means for rotating the color wheel in assembly;
a covering wheel of non-transparent material for covering the cover wheels in assembly said covering wheel having a recess;
means for mounting the plurality of color wheels and the covering wheel together for rotation of the color wheels relative to each other and the covering wheel; and
a scale disposed on the covering wheel, said scale being associated with the rotated position and consequently a given color gradation of each color wheel;
wherein;
(a) each color gradation on each color wheel has a radial extent less than the total radial extent of the wheel;
(b) the recess has a radial extent greater than the radial extent of the color gradations, so that the color gradations and an uncolored region adjacent thereto of each color wheel can be viewed through the recess; and
(c) said recess thereby serving for viewing any mixture of color gradations of the color wheels obtained by adjustment of the color wheels by said rotating means, in contrast to the adjacent uncolored regions.

Abstract
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.
