Have contrasting colours been placed next to each other?

Contrasting colours are those that are opposite, or almost opposite, each other on the colour wheel (Figure 2). They can suggest drama, tension or perhaps vibrancy, as in Afrodizzia, where the contrasting colours seem to add to the lively, joyous feel of the artwork. The effects of contrasting colours can cause the spectator to read a painting in a particular way by drawing their attention to areas of importance.
