Basic principle image
Dominance– From first seeing this picture i automatically thought of dominance, the way that the orange in this picture overpowers every other color is very visible. Even if you look at the bee which is supposed to be yellow and black, the yellow looks very much like indigo. I think the reason is because although the bee is yellow, the dominance of the orange took over some shading of the bee.
Unity– In this picture i also see yellow within the bee and on the pedals of the flower, however looking from far or your 1st glance it appears that the picture is all orange. From sitting here looking at the image, you can very much tell that the image has colors that are working in unity with orange and all-in-one allowing orange to be the dominant source of the union.
