I don't think this really has anything to do with science so I posted it here. It's a strange question, but I want to know what you guys think. Many things can be said to have two extremes... as in positive and negative. In this sense, 0 would be "between" -10 and 10. If you have three extremes instead of two, can any one of them said to be "between" the other two? For example, can yellow said to be between blue and red? With each of the colors being their own extreme, of course. Also does this question even make sense?
