Pastel drawing

This was a new technique for me,
Start with the basic drawing using a mid tone - a contour drawing essentially in a colour not related to the subject - in this case, persimmons.
I chose purple.
Next step is to fill in the lights and darks using complementary colours - again, not related to the local colour - i.e. greens and blue for sky etc.

The next step is to complete the drawing with local colour - i.e. the colour you can actually see, but leaving some of the under colour showing in a sketchy kind of way.

It was a very challenging exercise set by Suzi Davidoff, but it was rewarding as the finished work has a depth that would not be there otherwise.
