This is the roof color and brick is top picture

This won't help much, but your brick and roof are neutral and would go with almost any trim color you like. I'm pretty conservative, so would probably go with something close to the window color. Some of the new gray-greens might look nice.

The first thing to consider is what color the gutters come in...since they are not a design feature it will look better if they match the trim

Or are paintable

I am having a house built

Where are you in the process?

We are just now framing.

And the siding will also be grey just have not decided on light or dark. The front door and gable with columns will be stained a medium brown. Thats why I am wondering if that should stand alone as the feature. I thought about a dark grey for trim and gutters to match the roof and light grey on the siding in the gables or white trim and gutters with a darker grey in the gables. The garage door is a side load so should it be the same color as trim?

Here are a couple of ideas.

Make all the front windows the same.

Entry door seems really tall -- make the same height as the windows and add row of vertical brick above. I added sidelights as the door seems lonely.

Make columns larger.

Added full returns (circled in red on 2nd image) below gables with siding. If not, then a larger band of trim.

I would not use a different siding on the dormer.

You have chosen a mix of styles with a more formal brick and steeply pitched roof with short overhangs, but then adding the stained decorative truss and columns, and shakes on the dormer. I'll suggest not trying to mix in "craftsman" or farmhouse, and stay with the more traditional.
