Thanks--I like Marshmallow, too...had it on the walls in a previous apartment. The SW 2833 Roycroft Vellum is a great white, but is too off-white for this house...I've ended up with SW 7008 Alabaster for the walls--I painted some posterboards and keep moving them around to the different rooms as the light changes through the day. In this particular house, which is a small, woodland cosy-cabin with metal awnings...and can be dim...I needed something light...but not the glaring white of a Manhattan art gallery or the inside of an igloo. Alabaster is a light white with just a little warmth to it that picks up the warmth of the hardwood floors and seems to work well in all the rooms at all times of day. In this house it does read as a white and doesn't look yellowish. I have not used it before, so hope I'm right. I'll use SW 7005 Pure White for the trim (agree with jb14 about the semi-gloss finish--I always do eggshell finish walls and semi-gloss trim). I like the SW 7006 Extra White--a white-white with no added pigment--but it was just a little too in-your-face white for the trim in my rooms. The gray bedroom will be SW 7668 March Wind. Just seems like a nice, medium-light gray, which is pretty much the color that's already in there. Getting the paint samples and painting all the colors on posterboard was really helpful. The paint chips and looking at colors online...and reading online reviews...helped up to a certain point, but I would not rely only on that if buying paint for a major project.
