I'm reposting a comment from another thread on color selection. IMO, it's the best advice.
OP, do some research on color, color schemes, and some basics on how colors work together. Take your time. Paint stores have palette samples, where groups of colors that work together are combined on one chart. Ask them for any educational matter they have on color. They're out there, just ask. You want to be sure that colors flow throughout the house, so it's not a collection of individual rooms with different unrelated colors. If this is not your thing, or you don't have time, hire a color consultant. For a reasonable fee, they'll spend a couple of hours with you and save you from all the research. Asking for help with color on a forum is only going to produce a littany of colors that will most likely be of little help to you, especially if you're not real familiar with color. Once you understand color schemes, it can be as simple as plugging colors into a formula and picking those you like and work with decor. Good Luck.
PS When you get some ideas, then get some samples and apply them to small pieces of poster board, which you can then post around the room to get good ideas about how they look from various angles and up against different fixtures and such.
