Tried the "Purple to Pink", and can't say that it changes much with temperature. I put one hand under hot water and one in ice water, and there was only a very slight change.
On the other hand, it is a pretty rose pink with silver sparkles and dries quickly to a reasonably durable finish, so if you're ok with that, I guess any color change is a bonus.
