Future Research

The consequences for any primate foraging with or without the red-green signal depend very much on the relationship of color to the actual quality of their preferred food items. The integration of research in color vision in primates with sensory modalities, such as smell, taste, and texture is clearly vital, some of which is now proceeding (e.g., Dominy, 2004b; Riba-Hernandez et al., 2004). We hope that field technology (Lucas et al.,

2003b,c) will soon improve to the degree that it will be routinely possible to obtain quantified estimates of what primates sense and what they use those senses for.
