Green Curves. Oil pastels thinned with alcohol, on watercolour paper.
Another experiment I did with my oil pastels. As they are studio quality and quite hard to blend with the fingers I took a brush and my small bottle of isopropanol and blended them with alcohol. The difference between the single colours is amazing – red, yellow, orange and even the pink are still strong even when diluted, whereas the greens are losing their vividness. So I decided to draw the lines of the green curves with my polychromos coloured pencil after having sprayed a fixative on the painting.
