The painting below has lovely colors but it’s too busy. Everything is competing equally for your attention. If you look closely you will see in the foreground a mother quail and some chicks, which are lost in the flora. The father quail on the lookout in palo verde is also well hidden. Nice wild flowers, but also lost in the chaos. Before one can absorb the visual delights of this painting, their attention has already wandered off.
In an abstract painting the stimulus is ordering color, line, pattern, texture within a format. There is no obvious subject matter but one can still sense some measure of an affective quality.
Does the implied motion in this painting (below) make you dizzy?!
