Get average color of image via Javascript

Question

Not sure this is possible, but looking to write a script that would return the average hex or rgb value for an image. I know it can be done in AS

Answer 1

Figured I'd post a project I recently came across to get dominant color:

Color Thief

A script for grabbing the dominant color or a representative color palette from an image. Uses javascript and canvas.

The other solutions mentioning and suggesting dominant color never really answer the question in proper context ("in javascript"). Hopefully this project will help those who want to do just that.
