Working from the live model, Joanne Mehl demonstrates the mixing of color to create light and dark value patterns, and how to observe and create warm and cool flesh tones while maintaining value groupings. Many artists struggle with the creation of realistic flesh tones in portrait and figure painting. Since skin reflects light and color, the acute observation of warm and cool tones and perception of subtle hue changes are crucial. So is the ability to group values, in order to create the illusion of form.

Joanne Mehl has been a professional artist and instructor specializing in commissioned portraiture and figure painting since 1985. She currently teaches various classes and workshops at OSA. She is a graduate with Honors in Illustration from The Art Center College of Design in Pasadena.
