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.
See my post on using these colors for retro kitchen cabinets. And importantly note: These scanned image do not really get the colors exactly right; please pick up the printed palettes from your local dealer — and keep them on hand at all times!
You can also check out their 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.
