Background

I’d like to ask how important the background is for you in sets? I’m not talking about the location, like a bedroom, beach, or forest, but the level of detail in the background itself. For example, when one image has a tree and another one doesn’t, or when the walls are different colors. Is consistency in the background important to you, meaning the same background appearing in every image? Also, does the color scheme of the background matter — whether it’s purple, green, red, etc.?
