 For example, in the combination red, yellow, and blue, there are four colors between red and yellow, six colors between yellow and blue, and seven colors between bine and red; in the combination purple-red, green-yellow, and violet-blue, there are six colors between purple-red and green-yellow, six colors between green-yellow and violet-blue, and five colors between violet-blue and purple-red.
