This makes sense to me: as a display piece, I would think best a choice that allow the extraordinary rendering of the subjects pop out (e.g. the first, the black and blue), whereas in a home hanging, something gentler that would have comfort in a warm decor (or, alternatively a cool one) would make sense. If a shopper were looking for something for a warm bright room (like lots of kids' rooms) I think they might be attracted to a strong orange on a pale yellow background, for instance.
