Abstract:
An assortment of color elements is grouped within a plurality of color families which are organized in accordance with a bi-radial circular color chart (FIG. 10-A) and a columnar chart (FIG. 11-A). Except for the neutral-gray color family, a pair of boundary-hues respectively defines the extent of acceptable hue variation within each group, resulting in an included range of hue within each color family, and an excluded range of hue in between neighboring color families. A color map (FIG. 17-A) serves as an index for matching system color elements to various color media and mixing formulas. Variant-hue charts enhance color comparison and selection within each main color family by displaying variations of all three color attributes, that is, value, saturation, and hue, within a single chart. Variant-hue charts also consolidate color elements into a compact format, and provide a graphical user interface for computer color selection.

Variant-hue charts enhance color comparison and selection within each main color family by displaying contrasting variations of all three color attributes, that is, value, saturation, and hue, within a single chart.

Abstract:
A color matching and coordinating reference system for use by manufacturers and consumers of goods includes assigning a unique identification code for each of a plurality of colors. The identification code includes color family indicia, color value indicia, and color selector device indicia. Preferably, each color is assigned a unique color name as well. Manufacturers utilizing the system of the present invention label or otherwise associate each good with the identification code for each color used therewith to assist the consumer in matching and coordinating colors. Color selector devices and tables can be used by the consumer or manufacturer in finding matching colors or coordinating/complimentary color combinations.
Abstract:
There is disclosed a method for preparing a colour chart comprising the steps of defining a reference colour, specifying a range of colours from said reference colour, each colour being spaced by integral multiples of a preselected colour difference value from any other colour, the range spanning the colour space between the reference colour and some other colour.
Abstract:
A color indicating apparatus which comprises a plurality of concentric overlappingly arranged discs which are rotatably mounted on a pivot post which is carried by a base. Each disc is basically transparent and includes a plurality of windows with each window being colored to a certain percentage of screening. Each disc is a certain primary color with there normally being utilized four in number of discs with there being four primary colors. Mounted on the base is a locking device which is to be movable to engage with the peripheral edge of the overlapped discs so as to lock the discs when located in a selected position. The visually observable color of each window within the outer disc will assume various shades as determined by the color density of the overlapped windows.
Abstract:
Color wheel comprising 3 transparent overlaid discs with circumferential arrays of primary color gradation on each such disc, the colors being overlappable when the discs are moved relative to each other to define thousands of combinations and arranged so that in primary positions of the three discs, which are transparent, the color wheel forms perfect complements, triads, quartets, sextets, etc. and in almost all relative positions perfect and equal increments of analogous gradations of different color schemes (at all arcs where colors are changing). In each disc there is a 240-degree sweep of each primary color comprising a central 120 degrees of 100% intensity of the primary color decreasing in each 60-degree band of the side of the central 120-degree bands from 100% to 0 intensity at the outer edges of the 240-degree band. When the three such primary bands are aligned, they appear black through the combination of such colors where the said primaries are the primaries of the subtractive color system applied by inks or other mineral coatings, pigment impregnation or the like.
