In terms of art media, “pastel” refers to an implement consisting of a stick of pure color pigment bound in a suspension with a neutral hue and low saturation. The colors of pastel sticks are pure--the closest approximation to their natural pigments. The use of pastels in artwork provides untainted color. The hardness of pastels varies from quite soft to a crayon-like hardness. Pastels can be blended in much the same way oil paints can, but offer a crispness more like that of pencils or charcoal. Artists since the Sixteenth Century have employed pastels as a medium, treasuring the pureness of color that they provide.
