Simple reaction time is used to evaluate the processing speed and the co-ordination between the sensory and motor systems. Reaction time is influenced by various factors. Therefore, the effect of color stimulus in modulating the reaction time among young Indian males has been investigated in this study. A total of 50 healthy volunteers (young males) of age group 18-28 years were included in the study. The subjects were presented with two visual stimuli viz.; red and green light by using an audio visual reaction time apparatus. Using paired t-test for comparison of visual reaction time between red and green color in young males, it was observed that the response latency for red color was significantly less compared to green color (P < 0.05). From the present study, it could be suggested that the color stimulus has an impact in modulating the visual reaction time.
