Got a photo or image you want to use as the basis of your home's colour palette? Big Huge Labs' Palette Generator is a sweet Flickr tool that quickly and easily creates a "harmonious" colour palette. We especially like the various options available to access images to use; you can upload an image, link to your Flickr account, use a Photobucket image or just link to any other URL online.
Just take the hexadecimal results and convert them to CMYK using a colour conversion calculator and then head off to your nearest paint dealer with the results. You even get an accompanying quote with your generated palette ("Live life like you're gonna die. Because you're gonna. — William Shatner" was the nugget of wisdom we received alongside out palette).
