Our house is painted in Sherwin Williams Iron Ore with the trim in Pure White. We like the colors and are thinking of using the same colors (in an interior paint) for our second floor office. The plan would be to have two walls in Iron Ore and have the other two walls the Pure White. The trim in our house is Simply White by Benjamin Moore. Would it be too matchy matchy to use the same colors used on our exterior in an interior room?
