to summarize:
•Anish Kapoor gets exclusive rights to use Vantablack, the world’s “blackest black” pigment, which understandably upsets a lot of artists
•Stuart Semple responds by creating Pink, the world’s “pinkest pink” pigment, which he makes legally available to everyone except for Anish Kapoor
•Kapoor somehow gets ahold of Pink and posts an Instagram photo of his middle finger dunked in the pigment that Semple had banned him from using
•Semple gets ahold of Vantablack and posts an Instagram video of his hand making the peace sign with his fingers coated in Vantablack
•During this time, Semple also releases Diamond Dust, the “most glittery glitter,” again available to everyone EXCEPT Anish Kapoor

The best thing about Diamond Dust is that it’s made from actual shards of glass so Anish can’t just stick his middle finger in it again

This petty art feud is actually starting to look like it could be one of the most important pieces of performance art of the 21st century
