Experts had previously considered Tate Modern’s “Yellow on Moron” to have been executed by the Polish master, Wlodzimierz Umaniec (spelt Vladimir Umanets).
However, a novel technique known as a vandal-spectrometry has enabled scientists to detect traces of crudely applied oil paint beneath Umanets’ trademark scrawl.
This has prompted art historians to rename the work “Black on Maroon” and determine that it is part of Rothko’s abortive Seagram murals.
Inevitably, this reattribution has reduced the value of the piece. It has, however, increased interest in genuine works by Vladimir Umanets. This towering modern-day genius has been likened to the bastard spawn of Marcel Duchamp and Cy Twombly.
