摘要

颜色混合相加定律是所有颜色配色的基础，而物体色会随着光源的不同产生色差是光源色度学的重要知识点。通过三基色激光器混合出等能白色，并通过改变其中任一激光器的光通量，发现其混合色也随着改变，从而验证了格拉斯曼色彩混合定律。同时设计了同一物体在不同光源照射下，其三刺激和色度坐标的变化，验证了物体色跟光源色之间的关系。

Abstract:

The law of color mixing and addition is the basis of all color matching, and the objects’ colordifference generated by different light sources plays an important role in light source colorimetry.We used athree-color laser to produce a white color beam with the same energy ,and found that the mixed color variedwith the luminous flux of any of the lasers, which verified the Galassmann's color mixing law.At the sameime ,an experiment was designed to show the changes of the three slimuli and chromaticity coordinates of thesame object under the changes of the illumination of different light sources, which verified the relationshipbetween the object color and the light source color

Key words: colorimetry color coordinates tristimulus values
