This international standard is based on the relevant contents of the technical report CIE15:2004 Colorimetry of the New China Photographic Committee, and is consistent with CIE Section:2004, which adds the part about the color of objects with reflected and transparent light, and the content about the operation method of photography, adds the part about the photoelectric integral for reflection and transmission of objects, and adds the technical requirements for the operation method of photography. This standard replaces GT3907. This standard mainly changes with CB/T3579-1997 as follows: Revision of the "Specifications" content, modification of the general specifications for the measurement of object color: 1. The photoelectric colorimeter method is modified to the photoelectric colorimeter method for measuring color of beautiful tea; 2. The standard for comparative measurement of tea color is added: 3. The standard is designed and implemented by: Chen Shu, Ma Yu, Chen Yijiu and He Ping from the Shenzhen Institute of Chemical Technology, Shenzhen Haichuan Color Industry Co., Ltd. The versions of this standard are: G3/T 3979-1963, G8/T 8928--1937....

5.4.2 Method of expressing the measurement results
) The light source is the source of the spectral radiation (subtracted spectral radiation) and the color quality is the standard. The measurement is expressed in accordance with the G3T397 standard - CE1931 standard colorimetric system A, using the periodic stimulus value Y and the color quality standard Ta.3 to indicate the measurement result. In the C1964 standard colorimetric system, the purple stimulus value Y and the color quality standard Ta.3 are used to indicate the measurement result of the object color.
The self-visual comparison method is used to measure the color of the object. The result should record the color number of the sample and the color film that matches the sample: When the sample is not hot, the color of the sample is the best. 5.4.3 Test result description
