I finally picked my paint colors! The painters are coming tomorrow and will be painting the entire house (minus the basement) for the next 4-5 days... Thanks to forum members for answering my questions and offering advice :) in case anyone's interested, here are my colors... (all SW colors):

Hall/Foyer: believable buff

LR & DR: quietude

Powder Rm: copen blue

Fam Rm: blonde

Kitchen: blonde

Morning Rm (my kids' playroom): humble gold

Upstairs hall: believable buff

DD1's Rm: wisteria (shade of purple)

DD2's Rm: honeydew (light green)

Guest Rm: grassland

Kids bathroom: copen blue

Master bdrm: relaxed khaki

Master bath: grassland

If we eventually paint the basement, it will probably be whole wheat or ivoire... After testing soooo many samples, I hope we've made the right choices! But I'm happy w/ them. We'll see once it's all done ;)
