The strong colours in Inge Karsch's works seem to develop a life of their own on canvas by running and mixing. These sudden and random effects can be seen as a creative device to enhance the artistic intention. The artist loved these qualities of watercolours. They suited her spontaneity very well. In her watercolours, Karsch used the formal stimulus of the impression of nature for pictorial realisation. For her, these stimuli were landscape and tree forms, cloudy skies, light and weather moods, which she reproduced in strong, closed forms or filigree and delicate. She called them "Inge sky". It was not until about 60 years after her birth that the artist exhibited very successfully in solo exhibitions.
