I have been looking at colour work again recently. I suppose because it is more fun and maybe a little more artistic. I find that flesh tones are the real issue. Something I am trying to work with.
My first colour portrait (months ago) was the Joke, spcifically because of the lack of flesh tones. Now the real work begins. I have played around with lips and eyes, focussing on the colours rather than the details. Now I have to bring some real work to the table.

Derwent studios are my weapon of choice.

P.S. 16 Flesh Pink is a joke.
