So you have not enough money to attend a portrait painting class or hire someone to pose for you? But you’d really like to learn to paint skin tones?
Well, I guess you have enough money to buy some bread. Bread is a very good alternative to painting skin tones. See these Google search results on “bread” – the colors are in the orangeish hue family and – depending on the bread – not too chromatic. This tip comes from William Whitaker.
You should give it a try. A loaf of bread does not move, does not charge money and it makes a starving artist full.
