Colors can be understood in a logical way through the theory of opposition. This approach was recently developed by Dany Jaspers, giving a new and fresh approach to the theory of colors, in particular with a hexagon of colors close to Goethe's intuitions. On the other hand colors can also be used at a metalogical level to understand and characterize the relations of opposition, including the relations of opposition between colors themselves. In this paper we furthermore develop a theory of psychic dispositions, using the hexagon of opposition of colors. We present a hexagon of psychic dispositions based on colors that we compare in particular with Plutchick's wheel of emotions.
