The vantablack thing is a bit complicated because while it’s utterly ridiculous he’s the only artist allowed to use the substance (and is an utter prick about it, which is honestly the larger issue).

It has to be a somewhat controlled substance because it’s ridiculously carcinogenic, obviously that doesn’t mean you can’t sell it to other people it just has to be dolled out carefully and with instruction.

The pink is amazing though, I saw some in a museum once and it honestly looks like it’s lit up, cameras absolutely do not capture it. It just looks normal on cameras. It’s worth going and having a look if you ever have the opportunity.
