Red-green colour blindness

I saw a neat talk by a researcher from NYU’s Anthropology department about 6 months ago. I learned that monkeys use red body parts (face, chest, and butt etc.) to communicate with one another, and these parts might be red to take advantage of the red-green colour blindness of their feline predators, which cannot discern the red monkey parts from the green foliage above.
