I'm looking at the colors you have in your kitchen and dining room, and they are warm beiges. My eye keeps traveling toward the area rug you have in the foyer which looks gray, unless the colors are off on my computer screen. If so, I would try to find a warm gray that will work with the rug. What about hardware-which is a complimentary color to Latte and biscuit?

I really love the idea of keeping your foyer light, but you may need to find a color that compliments the other wall colors in your home. You can always change the rug.

The dark brown sample you painted on the wall is just going to make your foyer seem smaller and does not relate to your floors, rug, or furniture.
