据报道，旧世界的猴子和猿与新世界的猴子在区分可见光谱的颜色方面存在差异。旧世界的猴子和猿（猕猴，潘，Pongo）能够相当准确地辨别颜色，而一些新世界的猴子（Saimiri，Cebus）对长波长光的敏感性较低，辨别能力较差。这项研究检查了另一种新大陆灵长类动物，棉顶绢毛猴，Saguinus oedipus oedipus（Callitrichidae科）的颜色辨别能力。训练绢毛猴辨别一组孟塞尔色卡，既在同一色调类别内，也从训练色调两侧的2个色调类别中辨别。结果表明，棉顶绢毛猴能在可见光谱范围内准确分辨。人类受试者在类似的条件下进行测试，以比较他们的颜色辨别能力的绢毛猴。绢毛猴和人类受试者最难区分相同的色调。猴子的辨别能力与在自然环境中食用的水果的颜色有关。编制了一份新世界各种猴子通常食用的水果种类清单，并记录了水果成熟时的颜色。研究发现，大多数新大陆灵长类动物吃的水果，其成熟的颜色范围涵盖了大部分光谱。
Old World monkeys and apes have been reported to differ from New World monkeys in their abilities to discriminate colors across the visible spectrum. Old World monkeys and apes (Macaca, Pan, Pongo) discriminate colors quite accurately, while some New World monkeys studied (Saimiri, Cebus) have shown lower sensitivity to and poorer discrimination of long wavelength light. This study examined the color discrimination ability of another New World primate, the cotton-top tamarin, Saguinus oedipus oedipus (family Callitrichidae). The tamarins were trained to discriminate a set of Munsell color chips, both within the same hue category and from the 2 hue categories on either side of the training hue. Results indicated that the cotton-top tamarin can make accurate discriminations across the visible spectrum. Human subjects were tested under similar conditions in order to compare their color discrimination abilities to those of the tamarins. The tamarins and human subjects had the most difficulty discriminating the same hues. The discrimination abilities of the monkeys were assessed in relation to the coloration of fruits eaten in a natural environment. A list of the species of fruits commonly eaten by various species of New World monkeys was compiled and the coloration of fruits at maturity was noted. It was found that most New World primate species eat fruits whose mature coloration ranges across most of the spectrum.
