Two things have changed colour with me recently.... A few weeks ago, I bought a red lip gloss. By the time I got it home, it had started to turn white. As I watched it, it went completely white... Then today I put a fake Pandora bead on my fake Pandora bracelet. It was a purple glass one with white spots on the outside. When I got to work, I noticed that it was blue.......I thought I must have just picked up and threaded the wrong bead, as I have done before....but then, when I got home, it was purple again. I walked along my landing and at one end of the landing the bead was purple; by the other end it was blue. I kept walking up and down my landing and it kept changing colour, from blue to purple...VERY odd!! Anyone have any answers??!!!
