Shouldn't they all be the same?
I have a couple of cans. I can easily smell the difference with my eyes closed so I do not know which can Is which.My grand kids say there is no difference in smell or feel amongst colors. If you notice a difference, it could be psychological. Sort of like finding a lone red M&M candy amongst the mostly browns. I would wait to the end to gulp it down, but in actuality, it was the same chocolate candy that melted in your mouth and not in your hand, no real difference in taste.
