Series 3 Maintaining the Classic TraditionArt 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 lightfast 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.All our beautiful oil colours are permanentImproved permanency information and new pigments have enabled us to replace the toxic and fugitive colours with non-toxic and cleaner colours of superior lightfastness. Ongoing research and development is dedicated to maintaining or improving the permanency, safety and performance of our colours.Superior pigment-concentrated coloursPigments are chosen for purity and clarity. Art Spectrum oil colours give lasting brilliance and luminosity to paintings. The finest pigments are used in the maximum working strength to impart the best colour quality. It is not Art Spectrum's policy to substitute pure pigments with blanc fixe (a heavy filler) to simulate quality by artificially increasing the weight of oil paints.Colour MixingArt Spectrum's careful selection of pigments ensures clean colours and superior colour mixing without muddiness.Unique Colours Art Spectrum oil colours include a beautiful and unique range of colours developed for the Australian landscape.
