Add color option to differentiate the diffs between images #86
Description
diffColor assigns a color to the diff pixels between two images. It would be nice if there was an option to differentiate the color where the difference was detected. i.e.
- If a change in image 1 is not present in image 2 the diff of the color would be
#ff0000 - If a change in image 2 is not present in image 1 the diff of the color would be
#00ff00
