M. Graham & Co. Oil Paint - (1.25oz/37ml) Ultramarine Purple

Oil Color, made with walnut oil has been preferred by artists for centuries. It provides rich, vibrant color that is naturally more alive and brilliant. Free flowing and slower drying, this oil color enables delicate passages of finely blended color that will retain its brilliance over time. Graham Oil colors are made with Walnut oil because its unique refractive index and non-yellowing nature produces color that is more naturally alive and brilliant. In addition walnut oil allows us to increase the amount of pigment in each color, resulting in extraordinary richness, color saturation, brilliance and tinting strength.
