Unfortunately, changing the tint. Of blue is purple. I have complained about the product at Islandburner.com and would it also can give back (even after months now, but only within 5 days), but I would have liked a better quality for the price. Images are no longer after nine months have the shade, one has bought time "very disappointing" (inferior quality). Who changes constantly been his murals !!! ??? Would have rather wished that I get new pictures in good quality. The images have not been directly exposed to the sun's rays! Will need to look around for other images unfortunately :-(
