Erica, the existing color is very cool and the brick is warm. That, and the fact that you have two very different materials (brick & stucco) really breaks the house into two pieces. I would look at warming up the stucco and half timbers but leave the trim, columns windows, etc. white. A warm gray (taupe, gray/tan) which Briarwood is, would work well. This would join the two halves of the house into a more cohesive look.
