Compare your home to this one:
Larger trim/frieze board makes your color pop.
2. I like the idea of the shutters, because it is giving the field color to trim color a much needed boost. However, what I don't like is the view from the front of the home with just one shutter showing, and it being so bold, it stands out (not in a good way) without having repetition. I would increase the size of the window, remove the shutters and also add an additional horizontal frieze board over the garage area.
If that's more of a project than you want to take on, I would use a more subtle shutter color- like in the photo below:
On second thought- I would do both. Increase that small window size, AND use a subtle shutter color.
3. I would also increase the size of the trim throughout on all of the windows.
4. Notice how in the photo below the bay area is entirely painted in the trim color. It really should be all trim, with no horizontal siding in this area. That is also how yours should be. Yours might be like that- the picture is not clear enough forme to be able to tell.
5. I would also change the roof over the bay window to a copper roof.
6. I agree with you on the front door. It does look like the black hole. A bright red would be great.
Only paint the door in red, the side lights and trim in the off white trim color. While I was cutting and pasting, I went ahead and replaced your garage door. ;-) If the garage door is pretty- like the one below- have it be in the trim color- as long as you keep your current one- have it be in the field color. Contrast draws attention. If you don't want attention drawn to something, have low contrast. If you have something lovely, increase the contrast.
Good luck with your painting!
