Was müssen unsere Affen verhaltensgestört sein, war es doch viele Jahre offensichtlich, dass ihnen bunte Textilien besonders viel Spass zu machen schienen..

Oh nein, die Primaten sind "normal", sie nutzen ihre angeborenen Fähigkeiten! Sie brauchen die Farberkennung zur Futtersuche und -auswahl:
Seeing red: behavioral evidence of trichromatic color vision in strepsirrhine primates
We conclude that trichromacy may be only one of several routes toward increased foraging efficiency in visually complex environments.
und
Most primates have excellent colour vision that is quantitatively and qualitatively superior to that of other mammals (15-17). Colour vision is important for detecting and selecting ripe fruits from unripe and semi-ripe ones. However, fruit ripeness is not always indicated by colour or other external properties of the fruit so, in addition to visual inspection, primates will sniff, lick and touch individual fruits to assess their stage of maturity (18-19)
