Made in Oregon from pure artist pigments and refined linseed oil, Gamblin Artist's Oil Colors are a traditional, professional quality oil paint. Most of the American oil painters we talk with think of Gamblin's artist grade as the standard by which other brands are judged. Fairly stiff out of the tube, allowing you to build up texture if you choose, these colors quickly start to flow with the addition of a bit of medium or solvent. The colors are intense, tending toward transparency and warmth. And Gamblin paints are engineered for superior permanence and safety.
