Art can be about creating believable illusions.
The geometric overlay shapes don’t really make sense. If the circles and the yellow square were translucent acetate sheets, where the yellow square overlaps the red circle, the circle would appear orange through the yellow square. Where the yellow square overlaps the blue circle, the circle would look green. The only way you might see part of the blue circle looking blue would be if the yellow square had that shape cut out of it so that the blue color of the circle could be seen. The blue circle would have to be opaque to block the red circle from being seen. Sometimes reality doesn’t matter. I like the blue shape and it was fun playing with the primary and secondary colors.
