If you want help on color, you need to post a much better and clearer photo of the your house. The photo posted is so under exposed as to be impossible to see and understand the various elements of the house.

Thank you for the comment - I've updated the picture.

There are no windows on the left side?

Thanks - there are more windows. The photo just isn't updated.

BTW: Please forgive me but as an artist I need to make a correction. It's palette to denote colors. The palate is the roof of your mouth.

Thanks for the advice - I'll try to update the post. Any thoughts on the color selection?

Can you do all brick?

IMO, if you want "timelessness, and farmhouse modern", you will not be able to achieve that goal by choosing material colors for a brick house of this quite contradictory style. Inserting the garage into the front corner of the house I assume so it can fit on the lot is a major obstacle to your goal. The two story entry enclosure and hipped main roof are also contradictory to your goal.

These are some houses that I would consider timeless and farmhouse modern. Few are brick clad and those are often painted.

IOW, you can't make a Neo-eclectic into a modern farmhouse via colour selection.

But anything to avoid the ultra bland of the builder rendering would be an improvement. (But, please, no shutters.)

Choosing exterior colours based on an arms length or less view is misleading; that's not the way one sees a house unless you're building it.

Personally I would select the darkest gray siding you can, or at least the siding that is the closest in color to the brick. I would not want that siding on the side to pop-out the way it does in the photo. Definitely would not do white. What color are the windows?

As others have said there is nothing farmhouse about this house. I asked about the brick because doing all brick would look better than the clapboard with the brick.

As for color, the best thing to do is get large color swatches and bring it to your site and view them at the proper angle (ie: vertical) at different times of day. Color is affected by the light and its surroundings, so what may look beige in artificial light may look more gray in natural light, as an example.

Whatever you choose I would probably keep it as monochromatic as possible.

BTW, I don't consider gray timeless.

Grey is a current fad that has no staying power beyond any other fad or fashion. It will date quickly to the late teens for home construction historians

If you want timeless, ditch the hip roof for a gable, and ditch the far too dominant depressing double height entry entirely, and do the whole house in a handsome red brick like has been used for centuries.
