Even art world legend Yves Klein served his guests art as part of an art piece.
Klein is most famous for his creation of his own color, International Klein blue, and his consistent use of it throughout his works.

During one of his shows, Klein served patrons a blue cocktail which was a mixture of gin, Cointreau and International Klein blue. The visitors were in fact drinking part of the artwork and later would make their own.
Much to the delight of Klein, and the bewilderment of the shows guests, the pigment in the cocktails had turned their urine blue. Klein had marked his territory as an artist to be remembered.
Alison Knowles might not have the intention to make technicolor urine, but watching someone make a giant salad on the high line will definitely be a sight to see!
