Color matching devices and related methods

A color matching device includes a planar member comprised of a material chosen from a group of polymers and composites. The planar member has a specified thickness, first length and second length. In implementations the planar member includes an opening through which a painted surface may be viewed. In some embodiments, a color matching device, includes at least one planar member comprising at least one polymer, composite or combination thereof; wherein each planar member comprises a thickness, measured as a shortest distance between a first largest face of the planar member and a second largest face of the planar member, of between about .2 mm and 2 mm; wherein each planar member comprises a first length, substantially orthogonal to the thickness, of between about .5 inches and 8 inches; and wherein each planar member comprises a second length, substantially orthogonal to the thickness and the first length, of between about .5 inch and 14 inches, wherein each planar member further comprises a hang opening centered between a top surface and a bottom surface of the planar member and positioned closer to either a right surface or a left surface of the planar member; wherein the first largest face is orthogonal to each of the top surface, bottom surface, right surface and left surface; wherein the top surface is parallel with the bottom surface; wherein the right surface is parallel with the left surface; wherein the top surface is orthogonal to the right surface.
