Do you guys think I can paint my apartment walls and repaint them at the end of my lease?

This is an unintuitive place to ask and I will of course ask the leasing office before I do anything. I just wanted opinions.

If I get an exact color match of the walls in my apartments, do you guys think wampus landlords would be chill if I paint my apartment walls during my lease if I repaint them back to normal at the end before I move out?

Peel and stick wallpaper is more expensive than I anticipated (more expensive than a security deposit) and I want pretty walls.
