Sorry for misunderstanding, but will you be painting the entire building seen in the photo (and the garages)?

Modern houses like yours tend to be painted neutral colors. I'd go for white or off white with trim in different colors. I'd probably accentuate the horizontals, painting your porch railings a contrasting color. You can go to a website like SherwinWilliams, up load a better picture of your house and play around with color ideas.
