Species Name: Trachypithecus auratus Skin Color(s): Glossy black
The East Javan langur, also called the Javan lutung, Javan langur, or ebony langur is an Old-World primate in the subfamily Colobinae. As with all langurs, the East Javan langur is a social animal, living in groups of about 7 individuals, with 1 or 2 adult males in the group.
Species Name: Trachypithecus geei Skin Color(s): Golden to creamy white
Gee's golden langur, also known simply as the golden langur, is an Old-World primate found in a small area of western Assam, India, and in the nearby foothills of the Black Mountains of Bhutan.

Species Name: Rhinopithecus roxellana Skin Color(s): Grey-black or brownish-black
The golden snub-nosed monkey (Rhinopithecus roxellana) is an Old World monkey of the subfamily Colobinae. Golden snub-nosed monkeys are highly social animals that exhibit group behaviors known as fission and fusion.
Species Name: Leontopithecus chrysomelas Skin Color(s): Black
The golden-headed lion tamarin (Leontopithecus chrysomelas), also known as the golden-headed tamarin, is a lion tamarin native to Brazil. It is only found in fragments of lowland and premontane forests in the state of Bahia and is therefore considered an endangered species.
Species Name: Saimiri sciureus Skin Color(s): Gray
The Guianan squirrel monkey, also called the South American squirrel monkey, is a squirrel monkey found in Guiana, Brazil, and Venezuela. Saimiri sciureus was once thought to belong to the Collins' squirrel monkey and the Humboldt's squirrel monkey. Still, genetic research in 2009 and 2015 showed they were different species.
