Painter in oil, especially of East Anglian beach and coastal scenes. Having studied painting privately with Carl Brennir in Nottingham, Mellon went to to settle in Gorleston-on-Sea, Norfolk, at the end of World War I, where he had tuition for three years from Arnesby Brown. Their styles are similar, and Mellon became noted for his small, uncomplicated, breezy panels of the Norfolk seaside. His pictures are in public collections in Bristol, Yarmouth, Sheffield and elsewhere. He exhibited Fine Art Society, RA, ROI, RBA, Walker Art Gallery, Liverpool, and in other galleries.
