Decoration, however, isn't art, in my opinion. — Bitter Crank

I understand the point you're making and I agree all the way up until I don't. Your standard of art is tougher than mine. I think you're making it more highfalutin than it needs to be. I think it makes sense to say that art is anything that someone presents for aesthetic judgement. Then we get to decide if it's good art or not. For me, that judgement is based on what I experience when I look at it. As you noted, the experience I get from the mural in question is a pleasant appreciation for the color and composition and not much else. Yes, it could qualify as decoration. Can decoration be art? I think it can. I think decoration can even be good art.

Painting a wall color #F0EAD6, otherwise known as eggshell (type of bird not defined) is not art in any way, shape, manner or form. — Bitter Crank

Perhaps not, but it might be if you painted it Cosmic Latte as @jorndoe explained last week:

Hotels, hospitals, and clinics buy cheap reproductions of recognized art work to hang on the wall. They also buy framed photographs of trees and flowers, hills and mountains, water etc; truckloads of occasional furniture of various styles, even manufactured assemblages of bits and pieces that have a Duchampian 'found art' appearance, but are not. The overall effect is kind of neutral, not bothersome, sort of pleasant. — Bitter Crank

Actually, I find this kind of decoration soul-deadening. Not neutral at all, especially in hospitals and nice hotels where they are supposed to care about us. This type of decoration provides little messages over and over every minute - You are not worth putting any effort into providing a comfortable, attractive place for you to stay. You mean nothing to us.

Also - I like it. — T Clark

Actually, I find the image pleasant enough to look at. There are many a dismal hallway and dreary tunnel that would benefit from the application of this sort of content. Decoration, however, isn't art, in my opinion.

Decoration - wall paint, wall paper, plaster moldings, wood, miscellaneous objects, floor coverings ceiling treatment, lighting fixtures and light color, furniture fabrics and shapes, murals such as this, and so on contribute to the comfort or discomfort we experience within inhabited spaces. They require craft to create and their use involves careful aesthetic judgement, but the elements are not "art works" in themselves.

Painting a wall color #F0EAD6, otherwise known as eggshell (type of bird not defined) is not art in any way, shape, manner or form. Putting navy blue carpet on the floor is not art. Furnishing the room with goods from IKEA (or Ethan Allen) is not art. The room may be splendid: attractive, comfortable, relaxing, etc. but it isn't art.

Hotels, hospitals, and clinics buy cheap reproductions of recognized art work to hang on the wall. They also buy framed photographs of trees and flowers, hills and mountains, water etc; truckloads of occasional furniture of various styles, even manufactured assemblages of bits and pieces that have a Duchampian 'found art' appearance, but are not. The overall effect is kind of neutral, not bothersome, sort of pleasant. Just not art. Interior designers (not artists) have found that guests, clinic and hospital patients and visitors find the stuff on the walls usefully distracting.

Someone stuck in an exam room will look at the bland photo or painting on the wall because that is the least anxiety-producing thing in the room. "Guernica" would not be good. Bosch either.
