The Italian Natural Earth colours are created with pigments of antique origin that have always been used to make the colours that until a few years ago characterized the regional schools of Roman houses, of Venetian palaces, of the Umbrian or Tuscan hill- towns. The grain size of the dispersed pigment is larger than for traditional oil paints. The paste is dense, the appearance more opaque due to a different refraction of the light, the tone is more natural and the coat is thicker and more material. Italian Natural colours can be mixed with other oil paints. Slight discontinuities in tone are a guarantee of the authenticity and naturalness of the product, which contains no additional colorants of organic synthesis.
