The shells are mostly white with a few markings so I find them difficult to draw.
I have just finished reading an interesting, small autobiography by a painter, textile designer and manufacturer Bernat Klein called Eye for Colour (Scotland and Collins, London 1965). I was particularly interested in looking at the paintings and how Bernat Klein interpreted the colours in his woven fabric.
In his book Klein attributed the following quote to Klee:
The object of a painting is not to reflect the visible but to make the invisible visable.
