Getting a commission and I need some references but I think they may be too specific/ I don't know the keywords to search in boorus to find the result I want.

Basically looking for references of either 1 or 2 characters in the foreground, with another character in the background. The foreground character having more saturated colors and the background character usually being flatter. Ill attach the examples I have

Number of characters in foreground/background don't match but same idea.

Same here.
