ABSTRACT:
An implement for coordinating the colors of fabric and the like comprises a circular base portion of cardboard or other stable sheet material having therein a series of circular openings which are arranged in a circle concentric with the base member. Each of the openings is surrounded by an annular band of color, the colors of the band being selected in such manner that colors which blend are disposed adjacent one another while contrasting colors are located at the opposite side of the base member. Each of the annular color bands is divided into a plurality of sectors which are shades of the respective color. A central indicator member is rotatably mounted on the base concentric therewith and is of smaller diameter than the base member so as to be located inside the circle of openings and their respective color bands. The indicator member bears indices indicating the key color, adjacent blending colors and opposite contrasting colors. A rotatable opaque disc underlies the base member and has a single opening which by rotation of the disc can be brought into registration with one or another of the openings in the base member. In use the implement is placed on a colored article and positioned so that the article shows through the opening in the base member which is surrounded by a band matching the color of the article. The indicator member is then turned so that the index representing the key color is adjacent the band of the color of the article whereupon other indices of the indicating member indicate blending colors and contrasting colors.
