I came across a pretty cool little application, pic2color. The application allows you to upload an image or paste the URL of an image to generate a color scheme with Hex codes.
This is a terrific design tool for those creating websites and visual presentations. You can base your entire color scheme around a central image.
By the way, if you are looking to customize your own color scheme, check out this Hex Color Scheme Generator. You can paste the Hex code you get from pic2color into that generator to further customize your color scheme.
