《GB/T 3977-1997颜色的表示方法》由TC120（全国颜色标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了在进行颜色目视匹配或物理测量时颜色的表示方法，在1°~4°视场时，采用XYZ色度学系统表示；在大于4°视场时，采用X10Y10Z10色度学系统表示。本标准适用于一切物体色(包括反射色和透射色)和光源色。

Scope

This standard specifies the expression method of color when performing color visual matching or physical measurement. When the field of view is 1°～4°, it is expressed by the XYZ colorimetric system (CIE 1931 standard colorimetric system); when it is greater than 4° For the field of view, it is represented by X₁₀Y₁₀Z₁₀ colorimetric system (CIE 1964 supplementary standard colorimetric system). This standard applies to all object colors (including reflected and transmitted colors) and light source colors.
