Small-field tritanopia has largely been studied in terms of object color using color patches and light source color using narrow-band illuminants; however, wide-band light source colors, such as LEDs, have not been similarly investigated. In our previous study, the authors analyzed the color perception of LED point light sources with a wide-band spectral distribution by conducting color matching experiments in scotopic vision. Those previous studies were conducted on stationary stimuli and did not clarify the effect of motion on color perception of small-field stimuli. Regarding the color perception of small-field stimuli in motion targeted in this study, a color matching experiment of color perception of a moving LED point light source is carried out. The results differed from the color appearance of static stimuli in previous studies, and they suggest that color perception depends on the speed of movement.
