Abstract: Colored light may affect an individual’s ability to perceive color correctly, especially in low light environments. Previous studies suggest that colored light affects reaction time and awareness of a human within a vehicle. Additionally, color perception is likely associated with gender. However, more studies are needed regarding the correlation between light hue on the ability to perceive color correctly. This study investigated the difficulty to perceive block color under varying colored lights. The study consisted of 8 different participants, ages 9 to 44: 7 male and 1 female. The environment consisted of LED strips surrounding a black surface where blocks were placed. The perceived block color (red, blue, or yellow) under varying colored lights (red, blue, yellow, and green) was given a value of 1 if perThe Effect of Colored Light on the Perception of Red, Yellow, and Blue Pigmented Blocks Armaan Vaswani ception correctly matched the block color. A value of 0 was recorded if perception and actual block color were incongruent. Green lighting had an average of 0.25, the lowest of all light colorations. Additionally, the yellow block had an average of 0.125, the lowest among the different block pigments. These findings suggest that yellow block color perception was easily influenced by the environment. Additionally, red light can more easily affect the environment, influencing color perception. Future studies may investigate color perception in association with other light and object characteristics.
