Humans have trichromatic vision. However variations in gene can cause deficiency in color vision resulting to dichromatism. The aim of this work was to verify the real efficiency of dichromats to break colour camouflage. Total of nine colour-blind individuals participated in this study and the variable considered was the time to segregation of camouflaged targets. The interest was to compare the response time in several conditions of camouflage and the analysis was performed using the Cox proportional hazard model.
