Art Spectrum are Australia's most respected oil paints because they conform to the classic tradition. To make a permanent artists' paint, it is of the utmost importance to not only have light fast pigments and pure linseed oil (safflower oil in whites) but to ensure they are thoroughly milled as well. All colours are triple-milled to ensure that every pigment particle is completely coated with the vehicle, and evenly dispersed. This results in a stable paint film which has even surface tensions. Genuine oil colours characteristically smell of pure and natural vegetable oils.
