Of course they're not toxic for users or workers. I didn't mean that. Sorry if I didn't use the right word. I just wondered whether the impact to the environment for the production of one or the other pigment couldIt's more expensive, yes. In general, all special colors are more expensive than normal ones. None of them should be toxic - we're in Germany, I doubt toxic coating is allowed for normal devices here
be different, even if both are tolerable. That's maybe hard to know because it would take a complex tracing and evaluation of materials and so on... Normally people just makes sure to follow the rules and that's it.
It's not worth to compare impact beyond compliance. I didn't know the difference in price was due to stock volume, I thought it might be due to pigment production cost or something like that and thought if the ingredients were different maybe the impact too.
I was just looking for some reason to choose, since visually both are more than good enough and I didn't know how to break the tieup.
