The GB/T 11186.3-1989 standard specifies in detail the quantitative evaluation method of the tiny color difference between film Colors, especially the calculation of the color difference. This standard refers to the principle of film Color measurement (Part I) and the Color Measuring method (Part II), and calculates the differences in Color, lightness, chroma and shade between the specimen and the reference specimen based on the color coordinates in the CIE 1976 (LAB) color space. These calculations help to determine the degree of color difference in films, providing an important quantitative basis for color management in coatings and their applications.
