 In this period, Orellana reaches maturity as an artist, and his paintings reach the confluence of informal abstraction and the mannerism of an existential figuration that would seem even mystical in its representation.In this period, Orellana's work is enriched in terms of colour and texture, developing his artistic expression in a most definite manner.In 1964, Orellana participates in the opening exhibition of the Juana Mordó Gallery, in Madrid, Spain, with whom he was to establish a long-lasting business relationship.
