There is a psychological rather than a zoological reason why no species or subspecies of mammal is called ‘orange’: this term is subconsciously considered too demeaning even for a monkey. An example is the golden lion tamarin, shown here for comparison with a butterfly of similar hue, namely the orange albatross.
