Hector Richard Janse van Rensburg (born 27 October 1993),[2][3] better known by his pseudonym Shitty Watercolour, is a British painter and cartoonist who started posting watercolour paintings on the social media website Reddit in February 2012, and later expanded to publishing his work on his own website, on Tumblr and on Twitter.

[8] In 2011, he won a Wilkinson Quincentenary Prize, awarded by St. John's College, Cambridge, to the best entries in an essay competition for high-school students.

[9] Boredom and depression led Janse van Rensburg to revisit an old watercolour set and seek subjects to paint.

[11] Many people have mistaken the artist for Sir Quentin Blake, best known for illustrating children's books written by Roald Dahl.

[14] Janse van Rensburg worked for the BBC for a few months,[11][15] and has done paintings on commission for Intel, Lionsgate, ASUS, CNN, USA Network, BuzzFeed, and Prizeo.
