Abstract

A color computer wheel includes a white base member upon which four concentrically arranged discs are rotatably mounted by a central fastener, the discs decreasing in diameter from bottom to top and being made of a transparent sheet material. The top disc carries four concentric annular bands, each evenly divided into radial spaces. The three lower discs are each dedicated to a single primary color, and carry color bands arranged to register with the bands of the topmost disc, the color bands being divided evenly into radial spaces with progressive color shades thereon. The peripheries of the four discs carry legend strips, which identify the percentage of color in the radial spaces in alignment therewith.

Claims

1. A wheel for comparing colors and computing color combinations, comprising:

a light colored base member;

a set of four circular, concentrically arranged discs made of transparent material rotatably mounted upon and secured to said base member by fastener means passed through the common centerpoints of said discs, whereby said four discs can each be independently rotated in either direction;

said four discs being of progressively decreasing diameter moving from the lowermost to the uppermost thereof, the first topmost disc being a comparator disc, and each of said four discs having an annular legend strip on the periphery thereof that is not covered by any other disc, all of said legend strips being divided into the same number of circumferential spaces of equal arc length extending about the entire periphery of said discs;

the first, topmost comparator disc being smallest in diameter of said four discs and carrying thereon four concentrically arranged bands positioned inwardly of the legend strip on said disc, all of said bands being divided into the same number of radial spaces as the number of circumferential spaces in said legend strips and said radial spaces of said four bands being in register with each other and with the circumferential spaces of the comparator disc legend strip, the radial spaces of the first, second and third of said bands being clear and free of color;

a portion of the adjacent radial spaces in the fourth of said four concentrically arranged bands on said comparator disc also being clear and free of color and the balance of said radial spaces in said fourth band being tinted with progressive shades of black, the circumferential spaces of said comparator legend strip carrying legends indicating the percentage of black tint for each radial space in said fourth band;

said first band on said comparator disc carrying a legend indicating that it shows colors found on a second and a third of said four discs, the second of said bands carrying a legend indicating that it shows colors found on said second and a fourth of said four discs, the third of said bands carrying a legend that it shows colors found on said third and said fourth of said four discs, and the fourth of said bands carrying a legend indicating that it shows colors found on said second, third and fourth of said four discs, together with whatever percentage of black tint is found in the radial spaces of said fourth band;

said second of said four discs having three concentric annular color bands thereon, positioned to underlie said first, said second and said fourth of said bands on said comparator disc, each of said color bands on said second disc being divided into the same number of equal arc length radial spaces as the number or circumferential spaces in said legend strips, the radial spaces of said three annular color bands being in register with each other and with the circumferential spaces of the legend strip on said second disc, and being tinted with progressive shades of a first primary color, each set of radially aligned radial spaces of the three annular color bands having the same shade of primary color, and the legend strip circumferential space aligned therewith carrying a legend indicating the percentage of such primary color;

said third of said four discs having three concentric annular color bands thereon, positioned to underlie said first, said third and said fourth of said bands on said comparator disc, each of said color bands on said third disc being divided into the same number of equal arc length radial spaces as the number of circumferential spaces in said legend strips, the radial spaces of said three annular color bands being in register with each other and with the circumferential spaces of the legend strip of said third disc, and being tinted with progressive shades of a second primary color, each set of radially aligned radial spaces of the three annular color bands having the same shade of primary color, and the legend strip circumferential space aligned therewith carrying a legend indicating the percentage of such primary color; and

said fourth of said four discs having three concentric annular color bands thereon positioned to underlie the second, third and fourth of said bands on said comparator disc, each of said color bands on said fourth disc being divided into the same number of equal arc length radial spaces as the number of circumferential spaces in said legend strips, the radial spaces of said three annular color bands being in register with each other and with the circumferential spaces of the legend strip of said fourth disc, and being tinted with progressive shades of a third primary color, each set of radially aligned radial spaces of the three annular color bands having the same shade of primary color, and the legend strip circumferential space aligned therewith carrying a legend indicating the percentage of such primary color.

2. A wheel for comparing colors and computing color combinations as recited in claim 1, wherein said annular legend strips are each divided into twenty-one circumferential spaces of equal arc length.

3. A wheel for comparing colors and computing color combinations as recited in claim 2, wherein about one-half of the adjacent radial spaces in the fourth of said four concentrically arranged bands on said comparator disc are clear and free of color.

4. A wheel for comparing colors and computing color combinations as recited in claim 1, wherein said first, said second and said third primary colors are respectively blue, red and yellow.

5. A wheel for comparing colors and computing color combinations as recited in claim 1, wherein said four concentrically arranged bands on said comparator disc are immediately adjacent to each other, separated only by a circular line, so that comparison of the displayed colors is easily made.

6. A wheel for comparing colors and computing color combinations as recited in claim 5, wherein the innermost of said four concentrically arranged bands has a diameter greater than about one-third the diameter of said first, comparator disc, whereby to array said four bands concentrically about a relatively large central area for ease in comparing colors.
