Hume’s paintings are characterised by the use of simple blocks of vivid colour and elegant lines reminiscent of the late prints of French artist Henri Matisse. This work is from his Portraits series and depicts an anonymous whistler. Here, the artist explores the boundaries between abstract and figurative image making. The dark green elements at the top of this image resemble an indeterminate plant or tree and have the appearance of poured or dripped paint. The use of flat colour and lack of defining outlines lends the hand-like forms (at the bottom of the composition) a similarly ambiguous quality.
