STEP 6
Its time to change the color of right eye. Activate your “duplicate layer” first and then select right eye. I personally recommend you to use pen tool to select the right eye because of the hair that is covering her right eye. After selecting again use refine edge tool to refine your selection. Don’t bother about the hair that is covering her right eye. We’ll fix that later. This time also don’t forget to change the output to “new layer”. Press OK.
