Gamblin 1980 Oil Colors are made with the same dedication and pure pigments that go into their Artist's Oils. In addition, they use the same process of mixing, milling, filling, and hand labeling. In order to reduce the cost of oil colors, some manufacturers use gels and waxes to stiffen colors and replace traditional pigments with less expensive ones. Not Gamblin - their 1980 colors are formulated with pure pigments, the finest refined linseed oil and marble dust (calcium carbonate). With 1980 colors, artists experience colors that are true, without homogenized texture or muddy color mixtures. Their approach of using both traditional raw materials and processes ensures that artists experience the luscious working properties that they expect from their oil colors. Gamblin oil colors are luscious, intense, pigment-rich colors. Colors that do not succumb to age. Colors true to historic working properties, in a palette carefully constructed by America's premier colorman, Robert Gamblin. Made from the finest quality raw materials, Gamblin's oil paints invite artists to enjoy each color's unique tinting strength, transparency and texture.
