Exterior paint colors always seem be tough to figure out! I think it's because the light is always changing so drastically. I like to consult the major paint companies and see their popular colors and combinations to start. It's a great way to get a sense of what you like. Now that grey has become the go to neutral color of the decade I am seeing more and more grey houses. I think they look sharp! I love the pop that a grey house with white trim makes. Grey looks great on modern and traditional designs.
