How about a picture. With regards to the interior color, if they can stain it a good match to the floor and light isn't an issue, I think that is a warmer look. On the outside stuff, kind of need to see what the exterior looks like. That said, there is no one "right" answer.

Thanks for responding ro my post! The front door color will be iron ore (dark grey with brown undertone) and the garage doors will be mocha brown with a grey undertone. So the interior color could be white or iron ore. It's hard to see the colors inside. The walls and foyer floor have grey undertones.

I think that Iron Ore would be a bold statement for your foyer. If it goes with your wall color...go for it! However, the white looks very pretty, as well.

With regards to front door color, I think a nice contrasting color would work there.
