What is meant by irreverent colours? By the end of 1990s when Sen started to make frequent visits to India, he discovered there was no dogma attached to the way Indian people used colours quite irreverently in their social and personal life. Art critics have always considered Sen’s painting structure to be very western in approach. Although focus on colour has been Sen’s subject since his art academic years, but revisiting his native land when his artistic life had become mature brought him a different way of irreverently applying colour in his paintings today.
