I would paint it all one color, and please paint the garage doors too, right now, they are the very first thing that anyone looking at your house sees, and it isnt a good impression. It appears the only brick is on the front and may have been painted before, so yes, I would paint it the same color so the house doesnt look cut in half. I like a tan color similar to the picture above this post. 1st picture of second row, but, I would want the door painted the tan color too. You want people to see your front door, so add a nice color there. I agree, those posts need to be redone. They are way too spindly looking.

This home could easily be a mid tone blue. Something like SW Debonair. Paint brick, too. SW Heron Plume soffit, trim, fascia. Garage in Debonair.
