I am not color blind, and can easily see the difference between the two colors now that I know to look for it. However, I also had a difficult time in the beginning even realizing there was a difference between what could be safely taken and what couldn't. I think expecting players who aren't familiar with the details of the mechanic to recognize the shift between gold and orange icons is asking too much. Someone can call that hand-holding if they want.. I call it "why not just use a different icon for theft and cut down on the confusion/complaints".
