Energy of colours
Only recently I learnt that you can also take pigment off the crayons with a damp brush and use them as watercolour pans. I had to try this because I work rather small and the crayons are difficult to use for detailed work.
This painting has the size of a postcard. The intensity of the colours was a surprise to me. However I am still experimenting with the proper amount of water in the brush – lately I got the impression that I got it right when I took the brush tip between my fingers, giving it a delicate squezze (By the way this also applies to watercolour pencils!).
