Scope: This standard specifies the method of expressing color by using the CIE1931 standard chromaticity system or the CIE1964 standard chromaticity system. When the field of view is 1°～4°, the color is represented by the tristimulus value and chromaticity coordinates of the CIE1931 standard chromaticity system; when the field of view is greater than 4°, the tristimulus value and chromaticity coordinates of the CIE1964 standard chromaticity system are used to represent the color color. This standard applies to object color (including reflection color and transmission color) and light source color.
