Earlier this year, scientists created a new black so dark it absorbs all but 0.035% of visual light.
However, there is only one person in the world who is allowed to use it in art. That man is British artist Anish Kapoor, who made a deal earlier this year that gave him exclusive rights to the material.
Although Kapoor has exclusive access to the world's blackest black, he has now become the only person in the world banned from using the world's pinkest pink.
He was banned by fellow British artist Stuart Semple, who created the pink powdered paint and is selling it on his website.
Anyone buying the pink paint has to agree to a legal disclaimer, which reads:
By adding this product to your cart you confirm that you are not Anish Kapoor, you are in no way affiliated to Anish Kapoor, you are not purchasing this item on behalf of Anish Kapoor or an associate of Anish Kapoor. To the best of your knowledge, information and belief this paint will not make it's way into that hands of Anish Kapoor.
