Well, there are benefits to both white walls and colored walls. White walls make a room larger, make it easier to change decor and allow you to accessorize in a multitude of colors. However, it also gives a very sterile and in my opinion unfriendly environment. IT is very reminiscent of hospitals or doctors offices and often make a room look intimidating. When you have unlimited funds, white walls are good because you have the money to accessorize with pictures and different types of accent pieces. HOwever, if you are like me, someone that has a limited budget, I can inexpensively paint the wall an inviting color and have the limited accessorizes my budget can afford. Colored walls are an inexpensive way to make your room look more inviting.
My comment actually tended to more along the fact that he mostly wears black and his houses are mostly white. IT just seemed odd to me to go from one extreme to the other.
