Betty Jonker was active with a brush and palette from an early age. She began her artistic career as a drawing instructor. Following which she was co-owner of an advertising agency for 25 years where she produced designs for national and international organisations. In 2001 she stepped back from the world of advertising and so had more time to devote to painting. During her time in Benneveld she painted only in oils. While living there she created two landscapes: ‘akker’ (field) and ‘klaprozen’ (poppies).
After her health started to be affected by the oil paint she switched to acrylics. This resulted in a completely new style which is typified by a particular colour scheme. Using firm and resolute brush strokes, Betty Jonker creates paintings that exude joy and colour. Her work reveals a solid background based on her extensive experience in matters such as composition and the use of colour. This results in playful impressions of abstracted, enlarged flowers, people, landscapes and animals, that humorously reference human relationships.
