The blue is not good. For a small change switching all the blue to forest green would be nice. I don't love the outlining of the chimney. If the white were cream or tan that might be better. Too much happenin here. I'd also get that big shrub or tree away from the house.

I would also switch all of your trim to one color and get rid of the outlining of the chimney. Sage green looks great with your brick color and if you do not like green, you could go with a stronger blue, closer to navy.

Really nice home. With the gray roof, use a medium to dark muted gray for the entire chimney and black for all the trim and shutters. You can then use any medium muted shade of your choice of color for the exterior siding -- something you like that you feel goes well with the brick ... please don't paint the brick.
