The master's approach to art was that of plain art of Nagybánya. As Kohán was not deeply involved with this approach, he left the institution. His journeys abroad and time spent at free schools were significant in the development of his approach. He spent ten months in Paris in 1930-1931, later he visited Rome in 1935. These studies and his training himself according to an independent program changed his visual approach. In Paris, he was in search of a unique ageless scale instead of becoming involved in the fashion of the time.
