Q: "What color dining room set should I get? Just put new floor and painted (it's darker in person...it's a darker gray on the walls."
A: The room looks great! Congrats on putting this all together! Based on the neutral cool tones of the blue walls, the grey hardwood flooring, the white wainscotting paneling and crown moulding, the French style window and ornate dining chandelier, I would suggest the following options for dining furniture.
I have also include some window treatment and art or mirror reference images to tie the space together.
I have recommended some upholstered dining chair options as well as a bench option along one side of the dining table.
I think it's nice to mix and match chairs a little rather than using the same chairs at a table. You could use a round table or rectangular depending on the seating requirements.
