This strangely compelling set-up is the work of British Indian artist Anish Kapoor, purveyor of pigmented powder and onetime right holder of the world’s blackest black. This work, Imagine Blue, combines both, confronting the viewer with a pile of seemingly black powder in the middle of a red-lit room. But all is not as it may first appear and slowly the light turns white, revealing the powder to be a deep electric blue. Here the work is seen in a three-part installation at the Parque de la Memoria in Argentina in 2017, a thought-provoking contemplation of the devastation caused by the military dictatorship that ruled Argentina from 1976 to 1983 and the displacement of civilians it prompted.
