Abstract: The system consists of a board with sockets and an assortment of tetrahedral pegs having a regular obverse face and a reverse side in the form of a triangular shank that inserts to a matching fit in one of the sockets. When the pegs are inserted into the board or first element the adjacent faces of the pegs make contact so that no gaps exist between adjoining edges. Each of the faces, or a part of each face, if divided into more than one field, is uniformly tinted in one of a set of repeatable colors or polychrome or monochrome shadings.

Abstract: The consumer color reference kit of this invention is based on the four basic known process printing colors, viz., magenta (red), yellow, cyan (blue) and black, and contains nine major sheets each of which is dividable readily by the user into four minor cards. Each mirror card contains eight separate, different, distinct readily visually discernable color specimens. One of the major sheets, the primary major sheet, contains four shades (tints) of each of eight major colors or color groups, viz., red, orange, yellow, green, blue, purple, brown and gray.The remaining eight major color sheets are referred to as secondary and each secondary major sheet contains thirty-two different, distinct readily discernable shades (tints) of the same eight previously mentioned major colors/color groups.On one side of each of the nine major sheets, the color speciments are glossy (smooth).

Abstract: The color wheel palette includes a generally circular bottom plate with a raised annular shelf and a non-raised central portion, the shelf having a number of spaced color paint wells uniformly disposed therein which may contain color paints therein, while the central portion is divided by raised partitions into a number of color-mixing wells. The shelf wells are sloped downwardly and outwardly from their inner margins to help pool the paints therein. A generally circular cover plate of a slightly larger size and the same general configuration as the bottom plate is releasably stacked over the bottom plate to protect the paint. The cover plate has preferably three groups of three shallower color paint or color-mixing shelf wells which register with the shelf wells of the bottom plate. Each group is prefereably about 120.degree. apart and aligned with a different one of the three central portion color-mixing wells of the cover plate, which register with those of the bottom plate.

Series of marks corresponding to the expected biochemical test results for several specific microorganisms are preferably imprinted on the supporting member, making possible the identification of a single microorganism species from among several possibly present.

Abstract: Colored art work is produced by the use of a kit comprising a collection of small process color reference "tints" printed from selected combinations of three standard process colors, optionally with black, at selected percentage densities. The reference tints are arranged in groups with all the tints in one group having the same percentage, but varying combinations of process colors, and each of the tints is identified by a reference index. The kit also includes larger "cut-out tints" identifiable with individual reference tints and each of exactly the same tone as the corresponding reference tint.

Abstract: A shade guide for dental use comprising a pair of superimposed discs rotatable with respect to one another, one disc being a lower disc with a plurality of regions of different colors representative of different tooth discolorations of the patient, the other disc being an upper disc with a plurality of transparent regions representative of coloration of composite material adapted for being bonded to teeth. By relatively rotating the discs, the transparent regions of the upper disc successively cover the regions of different colors of the lower disc to provide a resultant coloration which neutralizes the discolored tooth and most closely matches the final coloration of the tooth of the patient.

Abstract: A color coordinator device for use in the selection of personal cosmetic colors and the like having predetermined relation to the skin and eye colors of the user. The device includes a shield member defining a pocket and having a generally radial viewing opening formed therein, and a color coordinator disc rotatable within the pocket and having quadrant shaped groupings of color samples thereon representing different shades or tones of primary skin colors which may be brought into view through the viewing opening.

Abstract: The present invention relates to a closed finger painting system that is adapted to be both clean and reusable. Provided is a rigid base member to which a number of closed, clear, flexible bags are attached. The bags are particularly adapted to be overlapped with respect to each other. Each bag contains a colorful, transparent fluid. The fluids can be manipulated within each bag by pressing the bags with one's fingers. When the fluids in more than one bag overlap, they create an optical impression of being mixed to create new colors. Therefore, an infinite variety of distinctive, abstract designs can be created.

Abstract: The invention is for color separation orientation gauges and methods by which they are used to produce a finished print in more than one color, the colors used being the primary colors and black. In the printing trade, the primary colors are at times referred to as magenta, yellow, and cyan. The color magenta is basically red, cyan is basically blue and, of course, yellow is basically yellow.The gauges utilized are provided with a predetermined number of dots disposed at various angles depending, for example, on the color to be eventually printed, which gauges are superimposed on a half-tone mask of which there are also a predetermined number of dots which are practically invisible to the naked eye. The gauges of the two embodiments of the invention are provided with special reference line dot densities and angles and legends to provide the color stripper with easy to use compact gauges for producing multi-color prints.
