This is something else I never learned at school. I was looking into whether there was a primary colour like system, but for smells.
And I learned something from Joseph Kaye’s thesis on “Symbolic Olfactory Display”, about a tribe in Senegal that has 5 categories of smell. I’ll give you the category and one or two examples from each.
It’s, uh, extremely culturally situated.
Anyway. Totally not relevant, but when I’m sitting in the library reading up on stuff, concepts like these give me ideas. Plus I just like it.
