Color standard arrangement
First Claim
1. A color order spacial system for classifyably arranging distinct color shades to be derived from a number of at least three pure colors (31,33,35) related to complementary colors (30,32,34) and a color white (6), said spacial system comprising;
- display means having areas (14 to
19) in a spacial configuration for receiving each of said color shades in a predefined spacial location,said spacial configuration defining an inner surface zone (8) and an outer surface zone (7),said color shades of said spacial locations varying in respective radial and axial directions of said spacial configuration in visually substantially equal gradations;
a. of density values extending from a spacial location for a maximum brightness value approaching the color white toward a spacial location for a maximum density value;
b. of tint values derived from substantially uniformly varying mixing ratios of at least two of the pure colors and of decreasing chroma values defined by an increasing gray tint value,the associated spacial locations for at least three pure colors (30 to
35) being provided near the inner zone (8) and the chroma values decreasing toward the outer zone (7) whereby the most turbid colors are on the outside of said spacial configuration.

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.
