IMO too much concrete and I have no idea what the front of the house will look like after the landscaping is in so maybe post those renderings

Try a sample of SW 6476 Glimmer for exterior walls; a pale green, but with enough color in it (I think) to not get washed out. Or go with Spinach White or Rainwashed. Maybe not neutral enough for your taste.

Blue is a great color for a house, you can do a grayish blue. Your house has a lot of details. It's not blah. One option for the vertical details is a paint color a few shades darker than the paint you choose, so you get some effect, but it doesn't stand out as much.

A warm color, like your current brown, never looks great with stark white trim. If you just changed the trim to cream, it would look better.

If you’re going gray, replace the taupe-y roof with gray shingles. Then you can paint your house a very pale gray or a light gray green.

The trim (window verticals, soffit rat-tails, garage doors, etc.) that is currently white should NOT be white. Paint the same color as your house.

Plant a tree in your front yard.

Update the railing and fence to add more texture and color. The fence blends in with the garage door so those could be changed out or painted as well

Your house has a Mission vibe about it. Very nice.

Paint the trim that you aren't fond of the same color as the siding. Blues, greens, grays and browns will all work. You could even go white or off white.

Paint the front in the same soft gray as the back and change out the roof color to blend. The white on the garage doors and fence is glaring. Soften it with a gray tone as well.

Here is a house with a color palette that I think would work on your house.

To me, it looks like a gray/taupe (putty color) with darker trim in same family. I'd replace garage doors with some with windows as on this house. I think this would work with your existing roof. You don't mention what your landscaping will be like so we are all just guessing.
