Abstract
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.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
200 words
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.
Claim 2
Dependent Claim
200 words
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.
Claim 3
Dependent Claim
46 words
A spacial system according to claim 1, wherein said pure colours (30 to 35) are provided by primary colours (31, 33, 35) and secondary colours (30, 32, 34), each determined by a mixture of two of said primary colours, said secondary colours thereby providing complementary colours.
Claim 4
Dependent Claim
54 words
A spacial system according to claim 1, wherein said spacial locations for the pure colours are circumferentially distributed, each pure colour defining a corresponding colour sector (14 to 19) with a pure colour location (30 to 35) of an associated one of the pure colours, said colour sectors having common limits (40 to 45).
Claim 5
Dependent Claim
66 words
A spacial system according to claim 1, wherein additionally to said spacial locations for the pure colours spacial locations for non-pure tertiary colours are provided, each of said tertiary colours being determined by a mixture of three of said pure colours, said spacial locations for the tertiary colours being located further towards the peripheral zone (7) than the spacial locations (30 to 35) for the pure-colours.
Claim 6
Dependent Claim
23 words
A spacial system according to claim 1, wherein said chroma values decrease to a pure grey tint provided in said peripheral zone (7).
Claim 7
Dependent Claim
47 words
A spacial system according to claim 1, wherein a spacial location for a color black is provided apart from said spacial location for the maximum brightness value, said color black varying towards said spacial location for the color white in pure gray tints in an axial direction.
Claim 8
Dependent Claim
37 words
A spacial system according to claim 1, wherein said density values increase in axial directions from the spacial location for the maximum brightness value towards said spacial location for the maximum density value approaching the color black.
Claim 9
Dependent Claim
46 words
A spacial system according to claim 1, wherein said inner zone (8) providing said pure colors (30 to 35) in a distribution in a circumferential direction with reference to said axial direction bounds an opening of said spacial configuration said opening being free of any color.
Claim 10
Dependent Claim
31 words
A spacial system according to claim 8, wherein said opening (8) of said spacial configuration is funnel like defining a funnel opening towards the spacial location for the maximum brightness value.
Claim 11
Dependent Claim
45 words
A spacial system according to claim 9, wherein, when viewed towards the spacial location for the maximum brightness value an opening of said funnel is irregularly bounded by a boundary, thereby providing zones of varying approach of said center zone with respect to said axis.
Claim 12
Dependent Claim
12 words
A spacial system according to claim 10, wherein said boundary is S-shaped.
Claim 13
Dependent Claim
27 words
A spacial system according to claim 8, wherein said boundary intersects the aximuth (6) in an intersection point providing the spacial locations restricted for the colour white.
Claim 14
Dependent Claim
58 words
A spacial system according to claim 1, wherein said inner zone (8) is elongated along said axis in a length extension, said pure colours (30 to 35) defining colours decreasing from higher to lower brightness values, said pure colours (30 to 35) being distributed along said length extension of the center zone (8) according to their brightness values.
Claim 15
Dependent Claim
