Attributed to the wrong Russian artist

Week 15's colours are Cobalt, Grey Blue, Ochre & Mouse

Natalia Goncharova held the auction record for the most expensive female artist until 2013, was famous within her own lifetime (something that eluded many female artists of the early 20th century) and was revered as a leader of the Russian avant-garde. She’s the featured artist for Coloricombo Week 15.
