I a have a broad background in chemistry so I know the basics. I was looking at a tanning product and this was the guy's big claim "All these ingredients have high pH levels of over 6! What does this mean? A pH of over 6 is the COLOR ORANGE!" Now, I wasn't aware that pH could change the color of chemicals when applied to skin or any other surface not created for testing pH. I mean if pH could be dertermined by just looking at the chemical color what would be the point of pH paper. I don't know, is his claim a bunch of crap? Besides arn't all the colors over 6 not orange, lol?
