Color calculator

Claim 2

Color calculator comprising means defining at least three endless continuous loops of transparent material relatively movable through 360° cycles in overlapping fashion, each such loop comprising in a minor area thereof, an array of color gradations in a primary color of the system as follows: 0 to 100% over 60°, then 100% over 120°, then 100% to 0 over 60°, balance blank, the 0 to 100% and 100% to 0 gradations being at substantially linear rate--i.e., equal (or other defined linear relation) increase (or decrease) in intensity per circumferential distance increment, means for indicating the center of each such primary color array on its respective loop, whereby (a) aligning the three centers 120° apart and in correct order produces secondary colors between the primaries, made of overlapping colors of the primary graded colors and incremental combinations therebetween, (b) overlapping the three centers produces a 240° arc of the combination of the three primaries (black in subtractive color primary system) of 100% intensity over a 120° central portion and 60° 0-100% to 0 at sides of the arc and 120° blank, and (c) other overlap combinations produce thousands of mixed colors which in all such arrangements show perfect complements, and perfect analogous step gradations around the loops, all the gradations of synthesized colors having natural gradation relationship.

Claim 3

Color calculator in accordance with claim 1 wherein the loops are flat discs, overlapping and having a common center of rotation, each containing color patches in circumferential array and at the same radial distance from the common center with complements thereby formed at diametrical opposites only.

Claim 4

Color calculator in accordance with claim 2 and further comprising 60° spaced indicia as radial lines on each disc in the primary color of that disc.

Claim 5

Color calculator in accordance with any of claims 1, 2 or 3 wherein the primary colors are made of dye impregnants in the respective loops, the primaries being cyan, magenta and yellow.

Claim 6

Color calculator in accordance with any of claims 1, 2 or 3 wherein the primary colors are made of pigment coloring on the respective loops, the primaries being cyan, magenta and yellow.

Claim 7

Color calculator in accordance with any of claims 1, 2 or 3 wherein the color gradations of each series are in distinct steps with separation between patches, continuing such steps of color (in the 100% region as well as the 0-100 and 100-0 regions).

Claim 8

Color calculator in accordance with claim 6 wherein the steps are 10% in each of the 0 to 100 and 100 to 0 regions of each primary color continuum.

Claim 9

Calculator device for calculation of, and education in, color relationships, comprising, means defining at least three endless continuous loops of transparent material relatively movable through 360° cycles in overlapping fashion, each such loop comprising an array of color gradations in a primary color of the system as follows: 0 to 100% over 60°, then 100% over 120°, then 100% to 0 over 60°, balance blank, the 0 to 100% and 100% to 0 gradations being at substantially linear rate--i.e. equal (or other defined linear relation) increase (or decrease) in intensity per circumferential distance increment, means for indicating the center of each such primary color array on its respective loop, whereby (a) aligning the three centers 120° apart and in correct order produces secondary colors between the primaries, made of overlapping colors of the primary graded colors and incremental combinations there between, (b) overlapping the three centers produces a 240° arc of the combination of the three primaries (black in subtractive color primary system) of 100% intensity over a 120° central portion and 60° 0-100% to 0 at sides of the arc and 120° blank, and (c) other overlap combinations produce thousands of mixed colors which in all such arrangements show perfect complements, and perfect analogous step gradations around the loops, all the gradations of synthesized colors having natural gradation relationship, the structural implementation of the foregoing means comprising, means defining at least three overlying transparent plates of endless form movable in repeat cyclic fashion, each such plate having a series of transparent color swatches therein, the color swatches of each plate being semi-transparent shades of a primary color, a different primary color being assigned to each such plate, the color swatches being arranged to provide overlaps of the swatches from plate to plate in different combinations of shades of the respective primaries including perfect complements and perfect analogous step gradations.

Claim 10

Calculator device for calculation of, and education in, color relationships, comprising, means defining at least three endless continuous loops of transparent material relatively movable through 360° cycles in overlapping fashion, each such loop comprising an array of color gradations in a primary color of the system as follows: 0 to 100% over 60°, then 100% over 120°, then 100% to 0 over 60°, balance blank, the 0 to 100% and 100% to 0 gradations being at substantially linear rate--i.e. equal (or other defined linear relation) increase (or decrease) in intensity per circumferential distance increment, means for indicating the center of each such primary color array on its respective loop, whereby (a) aligning the three centers 120° apart and in correct order produces secondary colors between the primaries, made of overlapping colors of the primary graded colors and incremental combinations there between, (b) overlapping the three centers produces a 240° arc of the combination of the three primaries (black in subtractive color primary system) of 100% intensity over a 120° central portion and 60° 0-100% to 0 at sides of the arc and 120° blank, and (c) other overlap combinations produce thousands of mixed colors which in all such arrangements show perfect complements, and perfect analogous step gradations around the loops, all the gradations of synthesized colors having natural gradation relationship, the structural implementation of the foregoing means comprising, means defining at least three overlying transparent plates of endless form movable in repeat cyclic fashion, each such plate having a series of transparent color swatches therein, the color swatches of each plate being semi-transparent shades of a primary color, a different primary color being assigned to each such plate, the color swatches being arranged to provide overlaps of the swatches from plate to plate in different combinations of shades of the respective primaries including perfect complements and perfect analogous step gradations.

Claim 11
