Richeson Casein, Ultramarine Violet Blue Shade (1.25oz)

Casein (kay'seen) is a quick-drying, aqueous medium using a milk-based binding agent, and is one of the most durable mediums known to man.

Known for their versatility and array of capabilities, casein paints can be used to create a variety of effects from the rich opaques of oil to thin watercolor washes. Because casein has an exceptional integrity of color and always dries to a perfect matte finish, it is unexcelled for art reproduction.

Helpful Tips for Caseins

• Choose a rigid, non-oily surface for your work
• Establish correct drawing and value patterns with a thin underpainting
• Dilute caseins with water to make washes & transparent glazes
• Casein colors, especially reds, oranges, and yellows, tend to shift after drying
• Lighten colors by adding more water or brighten them by adding powdered pigment
• To correct an overly dark area, cover it with a more opaque layer of a lighter color
• When working on a gessoed panel, correct any errors with an eraser or a 1:9 ammonia and water mixture
