Mostly safe unless it's light fast I like using my Polychromos coloured pencils cause they're super light fast, but not all traditional pigments are or can be. I have a Schminke watercolour set that is all light fast except this one super pretty purple that will fade in the face of the sun. I think though just warn people to not put it into direct sunlight. After that, you can't do much about it :/
