The analogy of the color wheel though is not quite perfect.
All colors in the spectrum can be made from the three primary colors, red, blue and yellow. But virtues aren’t like this. Honesty isn’t composed of some mixture of confidence and love; it is a virtue in its own right.
Thus perhaps rather than a color wheel, in this respect a better analogy is the periodic table of fundamental elements. In the periodic table, each element is listed individually with its unique characteristics; and through the periods (rows) or groups (columns) and blocks the relationship to other elements is shown.
