Conquering the local and foreign art galleries he promoted his unique Sri Lankan painting styles and the country’s name simultaneously from 1956. Like Geoffrey Bawa or Solias Mendis, today, Semege too has become a landmark in the history of Sri Lankan art.

Later on, while still at school, he passed all examinations held by the Royal Academy School of Arts, London and became the first child artist to hold a solo painting exhibition at the Art Gallery in 1957.
