Colour Palette Generators

When our developers need some colour in their lives and come to a roadblock, this is where we turn for palettes:

CSS Drive and Color Suckr's color palette tools are great for extracting colours from image URLs or image file uploads.  Between the two, CSS Drive lets you upload an image file, but Color Suckr doesn't.  Although, Color Suckr does have a cool fire-fox add on and bookmarklet feature that makes extracting easier.
