I have to agree with you, way too much white. I would leave the white trim, and maybe a light gray green, or gray blue, and once the painting is done, the door could use a nice bright color. You also might want to address the landscaping a little, and maybe set some colorful pots of flowers around your porch area.

Everything the same color does give the military barracks look to a building. I favor medium shade body colors that are in the grey/taupe range. But that can include a gazillion variations that lean toward some colorful tints. If they are grey/taupe enough, they usually look tasteful. (Sage or seafoam green is tolerable whereas Kelly green is not.) And then white trim looks cheerier and happier than dark trim. The body must be dark enough to contrast with the trim. Too light and the overall picture will look washed out. Too dark and it looks harsh. Somewhere in the medium range it seems to work best.

The converse arrangement (light body with dark trim) seems a Goth-like look ... a little pointed to me ... almost as if stabbing someone to get their attention. Dark body with dark trim seems gloomy.

Here are some basic ideas about arranging and organizing. Some trees are going to help the house look more protected and less exposed.
