I need 3 BM whites that will blend well together. The furniture has already been painted with Decorator's white (it's kind of vintage, shabby chic'ish so there is some White Dove dry brushed on here and there as well.)

Doing an all white room, so for the walls and trim I'd like whites that will blend well. The other colors in the house are grays with pops of light blue and lime green so I don't want anything yellow or too creamy with the white....

What would be a good choice for the walls that would blend with Decorator's white? I want lighter though not darker (which is why I'm not going with white dove for the walls) and then I was thinking Superwhite for the trim. We just replaced all of the molding and trim so I'd like it to stand out a bit.

So I guess the big question is: What BM white is 1/2 way between Decorator's white and Superwhite? I've heard good things about Simply white, white cloud and cloud nine. Any advice? Thanks so much!
