In May 2021 I bought four boxes of these tiles and installed them on my back open patio. Three of them have the black color, one has green. Of the three boxes of black color titles, titles from one box still looks great fortunately with their black sheen after two summers and one winter; black titles from the rest two boxes have fades into grey.A little over a year into their outdoor installation, I've not found any damage to any of the titles and that's good!
