I'd change the stark white trim. Perhaps to a yellow/tan that would interact better with the roof color, but someone who knows about colors would probably give you better advice.

You could load your picture into Photoshop and try different colors to come up with somehting less jarring.

I think your house looks nice. The garage door color looks a little off.

If it were my house, I might switch the white trim to cream, but the white looks pretty good.

Maybe the foundation needs to be painted a darker color?

Paint the garage door and shutters white. I think the blue of the garage door and the blue of the house are not a good match. Also would like to see more contrast between the shutters and house color, black to dark. Best of luck!
Nice house.

I agree, it's the garage door. I'd either paint it white or black to match the shutters. I like the shutters black. You mgiht also consider painting the foundation black. you can try playing with one of those online programs like Sherwin Williams has if you don't have photoshop.

Hope you dont mind but I couldn't sleep...soo...white garage door:
