Gamblin is an American oil paint company. The company has been making oils since 1980s. The company focuses on the development aspect of oil painting. I have not practiced much with oil painting, but the samples seem pretty solid. The best color the company has in the oil department is their black pigments. This paint has no black pigments. It is truly chromatically black. The upside to this is that the paint does not have any dirty fibers. Another interesting development is Gamblin fast drying paint. It is interesting seeing as though oil paint is preferred by painters who take forever to paint. Gamblin also produces Varnish. Varnish makes the painting shimmer and also helps protect the layers of paints.
