I am no designer but will say that the hardest color or non color to pick out is white. Be smart and hire a designer or even a paint store rep to come and look at your space. The couple hundred it will cost will save you 10x's that if you get it wrong.

We buy and sell homes and will tell you that w put the same white in different houses and you would swear it is not the same color. Everything from sun to surroundings effect white.

Be smart hire a pro. Once they start talking warm and cold this you will see how much is involved.

If you're looking for a true white, take a look at Sherwin snowbound.
