I'm copying this room except for a few things. I'm wondering if one wall should be brown and the other walls should be white or if the wall with the windows should be white and the other walls should be brown. Or should all the walls be brown?What color should I paint the walls?
i like it how it is in the picWhat color should I paint the walls?
Doing all 3 walls white then one room a different colour makes the room appear bigger, so i would go along with doing this instead of painting all walls the same colour.


Ive got it in my room expect all walls are white and one is red.


And it has made my minny room appear a lot bigger.
