Ok, clearly I was having a 'major obsession with gray' moment while making this post. But when it comes to half painted walls I think streamlined, simple, and clean is the way to go. And gray. Definitely gray.
I love how contemporary and unexpected the half painted wall looks [goodbye wainscoting. see ya chair rail]. Putting the darker color on bottom makes the ceiling feel taller, but I think the look works best when the ceilings are already high.
Oh hi, pink. It's nice to see you. You know I always need a little color!
I am absolutely loving the statement the wall makes in this room.
