Then you are left as I am, a house with no paintings, posters, wall decorations of any kind! All such things are clutter to me, and in fact, I even reject re-painting the walls.
I fear that I will notice the room is smaller, after that coating of paint.
I'm worried that now I'm signalling, that I'm not signalling, which is signalling now. Maybe.
So I support you, fellow non-signalling, and non-non-signalling kin! Yes, you can have paintings, just because you like them.
(Please don't tell me that I'm signalling by non-non-signalling!)
