| People with trichromatic color vision see not only four primary colors but also various intermediate colors between them. |
| Accordingly, the successful acquisition of fruits cannot be strongly tied to the evolution of routine trichromatic vision. |
| Similarly, we may have preferences for certain colors based on the primate trichromatic color visual system. |
| Theoretical modeling of fruit spectra into the trichromatic color space of catarrhine primates yielded similar results. |
| Primates, including humans, have three cones and can thus distinguish three of the primary color phases, giving us trichromatic vision, or high color resolution. |
| They have developed trichromatic vision, lacking in most New world monkeys. |
