Daler Rowney System 3 Original acrylics are highly versatile, water-based acrylic colours. They offer an excellent painting experience at an economical price. Only high-quality pigments are used in the manufacture of the System 3 acrylic ranges, offering significantly greater loading than in other acrylic ranges available in this class. System 3’s comprehensive range of colours offers excellent light-fastness (except for fluorescent colours), permanence, durability and covering power.All colours can be thinned with water to pale washes, or used directly from the pot or tube; each form dries quickly to create an insoluble film. The quick drying properties of the range enable the artist to work quickly, superimposing or juxtaposing colours without unnecessary fuss.System 3 Original colours are fully intermixable and suitable for interior use. 1 Litre.
