Individuals with color vision deficiency (CVD) face challenges in various daily activities that require color identification such as selecting appropriate clothing combinations, identifying ripe fruits or vegetables, et cetera. This study aims to identify the best illuminance artificial lighting for color difference identification among individuals with CVD in Indonesia (0,7%). The research focuses on the quantitative analysis of experimental data to assess the effect of different types of illuminance artificial lighting on color perception in participant with CVD. A controlled experiment was conducted with a sample of individuals diagnosed with CVD (Deutronomali, Deutronopia, and Protonopia), utilizing a standardized color difference identification test based on Natural Color system (NCS) as the color experiment tools. The participant was exposed to different artificial lighting conditions, including various intensities (illuminance) and different color background (black or white) for each category. Quantitative data is collected, focusing on the accuracy, speed, and total steps for completing the task under different artificial illuminance conditions. Statistical analysis, including analyses of variance (ANOVA) and correlation analyses, are conducted to examine the relationship between illuminance lightings and color difference identification in individual with CVD. The results based on the analysis of duration, number of steps, and accuracy, the optimal illuminance level for identification color differences falls within the range 400-500 lux. The second-best illuminance level falls within the range 300-400 lux. In conclusion, range 300-500 lux are the best illuminance level for perceiving color variation.
