Hello, Behr Silent White gives a very stark modern look to a home. With that being said, I don't mind it at all. In fact it looks fabulous with the right look. If you are transitional or modern I say go for it. If you have a more traditional look I would choose a warmer white like Behr Silky White. See below for some great concept photos of Silent White. Good luck!

it appears to be quite cool, and almost gives off a blueish cast. is this ok?

why don't you get a sample and paint a portion of one of the walls?

if you just want white, then do Ultra Pure White, or try Polar Bear white
