I painted arches when I designed the interior of a friends house. We talked a lot about what kind of art they want to see in their interior. The opinion was this: art should be calm, not independent (should not dictate and direct everything around it), it should gently accent and enrich certain places in the house. The composition should not have a lot of dynamics and expression, because at your home you want to rest and relax. Gamma is neutral. In general, art should have some versatility, they said, so that when you move it can be easily relocated to a new interior.
Here is one of the results of the experiment.
