The Vallejo Pigments, a selection of natural earth and synthetic pigments, were chosen for their durability, their excellent lightfastness and the extra-fine grinding of their particles, which facilitates the mixtures and their application on models and dioramas. The palette of pigments includes a range of colors chosen to represent the wear and erosion caused by the conditions of harsh use and stress on vehicles and buildings, to the dust that clumps in the tracks of tanks , to reproduce the rust on the armor and the diverse effects of climate and geographical operating conditions.
Pigments can be applied in dry form directly to the model with a brush as they have excellent adhesion; they can also be fixed with thinner when used to depict dry mud or accumulated dust. With pigment binder, the pigments can be used to create volume such as accumulated dirt and mud. Painting tools are cleaned with water.
