With the basic knowledge of DKL color space and isoluminance adjustment in chromatic motion research,we reviewed the characteristics of chromatic motion perception and hypotheses on the chromatic motion based on different processing levels of receptors,pathways and cortex,and then looked forward to research trends in this field.

This paper adopts the experimental results of the luminous efficiencies of non\|spectral colors in China to study the different mesopic equivalent luminance of non\|spectral colors and propose the corresponding model of equivalent luminance.

Beginning with sports lighting,this paper discusses the effects of chromatic light on pupil size,and variable ratios of equivalent luminance and luminance of variable chromatic light.
