Can you post better elevations -- maybe from a computer instead of your phone?

I need help deciding which type of stone a color could look good with the siding color I’m thinking of choosing.

Generally you want to choose the stone first, then siding color to complement.

I’m in the process of building a house

Have you started building? What can you/are you willing to change?

Is the stone planned for just the front? Is it required for any reason?

Continue the stone, in some degree, all the way around the house.

I made a bunch of changes.

Spread windows apart. Replace center window above door. Taller first floor windows. Smaller windows on wings match 1/2 the 2nd floor windows. No small overhang. Stone only on foundation, or stone on both floors (front and 2 side walls) of the main part of the house. Remove gable. Larger columns. Square doors -- I'd do a single door.

Forget the stone. All it does is cut the house in half and make it look like a builder's tract house. If you must go with stone, do like PPF shows and carry the stone around all four sides of the house so it looks like it's part of the foundation holding up the house.
