Oil paintings or canvas oil painting are usually selected to be a part of any of the commonly used rooms at home. Though every room should have a selected oil painting for whichever room is intended for.
For instance, kitchen can have ingredients or spices used in cooking. In the dining room, there can be some fruits or the Last Supper. In the living room, anything colorful that can provide a vibrant glow when looked at.
Just remember that paintings should be able to evoke good and positive feelings and relaxing thoughts to calm down a usually panic-striken morning.
