Through field observations in Gabon, literature comparisons and experiments in captivity an attempt was made to assess the biological significance of the colourations of the Equatorial Forest Baboon. It appears that the various coloured body parts fulfil different functions, although the same pigments occur throughout: The posterior colouration of the leader has a signal function for the troup, the penial colouration has a dominance function, and the facial colourations have evolved through rivalry of adult ♂♂ for ♀♀ and food.
