I love the Sherwin Williams Suburban Modern paint palette. I've used a couple of the colors in my house, and they've always been spot on! Note, they have separate interior and exterior palettes - but don't let that stop you from using an exterior color inside your house, and vice versa.
Check out the web pages - and be sure to download the entire brochure - it's a great feature and let's you see good-sized color chips, I'm really impressed. When I buy their paint, I've always purchased the best quality possible. If you want to save some money, wait for a holiday weekend, it seems like there's always a decent sale.
