Nigel Buchanan is an Australian illustrator based in Sydney, whose clients include The Wall Street Journal, The New York Times, and Time magazine, among others.
His illustrations are created in a broad range of degrees of stylization and conceptual abstraction, but are always delivered with considerable graphic punch. Buchanan knows how to use both muted, neutralized colors and bright primary passages to achieve just the right effect for his subject.
I particularly enjoy the way he brings gradations and changes in color out to the edges of the planes within his forms, giving the suggestion of strong geometry beneath his often fancifully shaped people and objects.
You can find example of his work on his website, the site of his artist’s representatives, Gerald & Cullen Rapp (where they are reproduced somewhat larger), as well as on his Behance page (where they are sorted by subject), his Illoz portfolio and Tumblr (where a selection of images are reproduced larger than elsewhere).
