ABSTRACT:
In order to overcome difficulties which arise when making conventional color charts and color spaces, a torus-shaped spacial structure is used as base body for the arrangement of color tones.
The gray tones are located at the outermost jacket area thereof and the clearest colors are located at the inner jacket area thereof. In the inside of the body, the colors extend through all color tone steps from the clearest up to the gray tones. By means of an iterative method for the arranging of color tones in the torus, it is possible not only to discriminate the color tones for the human eye equidistantly, but also to represent the brown colors reliably.
