Gamblin 1980 Oil Colors are student-grade paints, made with the same dedication and pure pigments that go into Gamblin’s Artist’s Oils. In addition, they use the same process of mixing, milling, filling, and hand labeling. Some manufacturers use gels and wax to stiffen colors and replace traditional pigments with less expensive ones. Gamblin’s approach is different. 1980 colors are formulated with pure pigments, the finest refined linseed oil and marble dust (calcium carbonate). More affordable colors have been made with these three ingredients since oil painting began. With 1980 colors, artists experience colors that are true, without homogenized texture or muddy color mixtures. Gamblin’s approach of using both traditional raw materials and processes ensures that artists experience the luscious working properties that they expect from their oil colors. 1980 Oil Colors are available in 37, & 150 ML tubes.
