Light colour paint can really do a room good! Some of these dark colours lead to depressive thoughts after a while. Unless it is a black chalk wall for a creative mind that wants to scribble and draw on it!
I can only imagine, some people are so used to what they have at home. I always think back at my brother living in the UK with their heated homes, and then back here in South Africa where the homes are the exact opposite. Such a hard thing to cope with actually haha.
Have a spending new week!
