I'd like to build a webapp in Rails in which I'd like to determine every pixel's color of a given image (JPEG). Is there any possibility to do that with Rails or JavaScript? The goal is to write an algorithm which determines the "middle color" of the image and uses it for background color of the site.

Any suggestion would be appreciated.
