“Every character has a specific color — it’s a nice way of giving people their own identity. We use color like comic books do, with each character staying in their lane as far their palette goes: T’Challa is purple, Okoye is red, and Nakia is green.
[Nakia] is the No. 1 warrior in the River tribe and her look was inspired by the Suri tribe in Africa,” says Carter. “Green signifies water, a coastal community, leaves and plants — they live in a lush area, as opposed to the perception that Africa is arid and dry.” - Black Panther costume designer Ruth Carter
