Gamblin 1980 Oil Colours are made with the same dedication and pure pigments that go into the Artist’s Oils. 1980 colours are formulated with pure pigments, the finest refined linseed oil and marble dust (calcium carbonate) to make a more affordable oil paint - More affordable colours have been made with these three ingredients since oil painting began. With 1980 colours, artists experience colours that are true, without homogenized texture or muddy colour mixtures.
