Rublev Colours Pigment Luberon Raw Sienna Light - 4 oz

Iron oxide earth pigments, often called, are an important group of inorganic pigments derived from minerals. Iron oxide pigments are yellow, red, and brown, but artists know them as ocher, Sienna, red oxide, and umber. Unlike manufactured pigments, the colour of iron oxide earth pigments varies with the composition of the particular segment of earth from which they come. The color of Sienna earth pigments is derived from three constituents: the principal colouring ingredient, secondary colouring ingredients, and a base. The combination of these ingredients produces the particular colour of the earth. The innumerable forms and variations these ingredients can combine result in a wide range of yellows, reds, and browns.

Warning: The pigment is considered non-toxic, but care should always be exercised when handling the dry powder pigment so as not to inhale the dust.
