Blending Oil Pastels Techniques
Blending is a painting technique where two different colors are slightly mixed together when wet, giving a smooth transition from one color to the next. The transition color will be a product of the two blended colors (i.e if you are blending blue into a yellow, the transition color will be a green).
Blending requires the paint to be wet, which is a problem when painting with acrylics as the paint tends to dry extremely fast. The blending technique is much more popular with oil painting, as the paint stays wet and versatile for much longer.
