M Graham professional grade artist oil color is ground in walnut oil because of its unique refractive index and non-yellowing nature.  Due to this, our colors retail their clarity over time and are free from the discoloring associated with other drying oils.  The increased pigment load in our color results in extraordinary richness, color saturation, brilliance, and tinting strength.  

You can be completely solvent free by using our oil paints and mediums.  You do this by using walnut oil to thin your paint as well as clean your brushes thus eliminating the need for solvents.

Experience the quality and consistency of M Graham paint across all four of our paint lines: watercolor, gouache, acrylic, and oil.  You can move seamlessly between mediums with our uniform color and color continuity.
