Remove ALL the shutters, they don't suit the house

I'd actually get rid of the sideburn shutters beside the large lower level window, and just landscape around it.

Here are some green combinations. BTW you should ONLY be considering STAIN NOT paint for the wood on your house. Metal get paint. Wood gets stain so it doesn't peel off.

Take the shutters off the combo picture window. They don't belong there.

Carefully size your shutters so they match the size of your windows.

I would suggest SW Oak Leaf Brown. IF you need a contrasting color BM Brick House Tan

The light color would brighten up the inside of the porch. (I would paint the porch ceiling a very light blue)

I too would remove the shutters, too cute, not suitable for the size of the windows.

Green with the ochre tones of your brick and wood accents for shutters and garage door would look great

Personally I don't like dark colors over light colors because I think it looks top heavy, but you do you. I would look to use a color present in the brick, but lighter than what you currently have.
