Description

technical field [0001] The invention belongs to the technical field of gem color comparison, in particular to a Munsell color card color comparison device used for gem color comparison. Background technique [0002] Munsell physical color card is a kind of physical color card for color comparison, which can be applied in printing, textile and construction fields. At present, in the traditional color comparison process of color cards, it is necessary to take out different color cards one by one, compare them with the corresponding objects to be compared, and finally determine the color of the sample. During the color comparison process, the user needs to take out the color card and compare it with the gemstone to be tested one by one, which will produce a repeating comparison process. The color of the sample and the color card will be compared in the visual memory of the tester within a certain period of time. A color comparison has an impact, and it takes a long time, resul...
