Betsy Dillard Shroud demonstrates the use of Grumbacher mixing mediums to provide depth, brightness and richness to your paintings. Shroud works with Mixing Medium #3 for mixing and blending colors to increase their intensity. The use of Mixing Medium #3 allows paint to move around more fluidly. Linseed Oil enables greater clarity and brilliance to color by improving the flow and increasing the gloss of oil colors. Shroud also works with Turpentine to provide an example of how when used sparingly, it can make colors dull.
