Color Thief won’t work …

I’d like to use Color Thief, a script which allows you to extract the dominant color of an image.

Unfortunately I’m not able to get the code to work. I’d like the dominant color to be the background color of a div called


Here’s what I have so far:

Updated code / transfered to my own server due to cross-linking issues:


var sourceImage = '';
var colorThief = new ColorThief();


<div id="mydiv"></div>

Thanks for any help!


Try this based on your code and a mix of everyone's answers. You need to wait for the image to load before using Color Theif. The color for photo1.jpg should be [125, 190, 193]

Thanks @Shadow Wizard and @ejegg

See Official way to ask jQuery wait for all images to load before executing something

EDIT: Ok use this fiddle which works
