“in the Philippines there is a group of people called the Hanunoo. They divide all colors into just four—mabiru, malagiti, marara, and malatuy. Marara, for example, includes those colors that we call red, orange, yellow, and maroon. If you show a Hanunoo man a red shirt and a yellow shirt he will tell you that they are both marara. If you press him he might add that the first is “more marara” or the second “weak marara,” but they will both remain as marara.”
