Out of curiosity, I was looking at the composition of Perylene Green. Perylene is a chemical compound and is a polycyclic aromatic hydrocarbon (PAH). PAHs have a low degree of acute toxicity BUT are considered carcinogenic, nevertheless. This article states Perylene is a non-toxic pigment. I am not a chemist, but you should be questioning the validity of comments made by contributors who are simply taking their comments from who knows where.
