Abstract:Cone cells are active under mesopic conditions , which means color naming ability will be one of the important tasks in footpath lighting .This paper , evidenced by indoor simulation experiments in which the subjects are asked to recognize four pairs of color swatches at a distance of 4m, explores the effect of SPD of LEDs on color naming ability of pedestrians .The result shows under the different adaptation lighting environments, correlated color temperature has statistical significance to color naming .When it is at 4000K, the accuracy is the highest and the error of judgment is slightest , 2700K and 6500K taking the second place .Meanwhile , the experiments also obtain the influence of correlated color temperature on single color.
