If you are buying water crystals intended to be used for feeders, then any colors in them is likely to be food safe dye. If you are using water crystals intended for plants or other things, then you are going to have to read the package to determine what dye was used or ask the manufacturer. Likely still food safe IMO.
There are plenty of post in this forum claiming that water crystals used to keep crickets and other feeders hydrated somehow made it to their frogs and caused death from impaction. So you might should search for those and form your own opinion. I still use water crystals for my crickets. I dye it with food coloring sometimes.
