I have download it and run ImageColorPicker-master/example/index.html file in chrome. Working fine in firefox but not working in chrome Version 61.0.3163.91 (Official Build) (64-bit) in ubuntu.
In chrome console, it gives following error
ImageColor Picker: Unable to access image data. This could be either due to the browser you are using (IE doesn't work) or image and script are saved on different servers or you run the script locally.
