Why are there no browns on the colour wheel?
@woo The wheel is merely one end of a cylinder.
@mavit What happens, longitudinally? Light-dark?

@woo It depends on your choice of projection, but sometimes, yes: https://en.wikipedia.org/wiki/Color_model#Cylindrical-coordinate_color_models
@mavit To explain: I've been watching music theory videos and I wasn't happy with an analogy of the "cyclic RGY colour wheel" with the "Circle of Fifths". You can see how well my attempts to prove him wrong are going but, y'know, SCIENCE! :-/
@mavit I'm also into n-dimensional graphs though, so that's an added bonus.
@mavit Ooh, thank you! This all started with music theory and I've been thinking about a conical spiral model for that.
