Kitty...I loved my former home - open plan, etc. may I ask you a question? Ppl looking at contemporary homes expect more than white. I'd use a different neutral, maybe in different shades for different rooms, but always letting the house flow. I've seen some nice subtle grey tones in Houzz, although I've added a 2-tone beige photo from my current 2 story colonial. Have fun dressing your contemporary.
