Burnt Sienna

Grumbacher Pre-Tested oil colors are made with but one purpose: to give artists paints which are pure, brilliant, intense and permanent. To carry out this aim, the Grumbacher Research Laboratory selects for Pre-Tested colors pure, permanent, intense pigments and combines them with the finest oil to produce artists' colors of superior quality. Special care is given to the preparation of each color to insure that it is ground to a uniform, smooth consistency for use with brush or knife. Throughout the entire process of manufacturing, Pre-Tested oil color is checked by the laboratory and by staff artists. Each lot is pre-tested after aging to insure conformity to the strict standards set for it regarding hue, brilliance, texture, working quality and brushability.
