Artist Stuart Semple, creator the world’s ‘pinkest paint’, has a new invention - the world'd 'glitteriest glitter'. The product has been made available to everyone, as long as buyers ensured that it would not make its way “into the hands of Anish Kapoor.” According to Semple, the renowned British-Indian sculptor didn’t deserve access to the colors, as he had been given exclusive rights to ‘Vantablack’ – the world’s blackest ever black – in 2014. Should colors be exclusive? Will this tactic work? What is to be made of wars in the art world? Jeff and Anthony tackle these questions and more.
