Rublev Colours Italian Dark Ocher is hydrated iron oxide—the principal coloring agent in ochers. This color is based on the natural mineral goethite associated with varying proportions of other minerals such as clay, chalk, and silica. They differ from other ochers in that they contain water. In other words, the iron they owe their color is hydrated iron oxide. Natural yellow ochers are semi-opaque, permanent, and have good covering power.

NotesSome separation of pigment and oil may occur in Rublev Colours Artist Oils and is a natural process when no wax or stabilizers are added to paint to prevent this from occurring.
All images of color swatches on this website are only approximations of the actual color of the oil paint. We have carefully matched the color in these pictures on calibrated color monitors to the actual color. However, your results may vary because of the wide variance in color monitors.
Color Swatch Note: The color swatch was created with a thick application (left side) of color and a tint (right side) made with equal parts of color and titanium white and applied on acrylic primed cotton canvas.
Drawdown Note: The image of the "drawdown" contains a pre-mixed paint film of 6 mils (0.006 inches) thickness applied to a standard test card to examine color consistency, opacity, and other qualities. The drawdowns show the full-color strength (mass tone) on the left and mixed in a 1:2 ratio with titanium white on the right. The bottom area of the drawdowns is scraped to show undertones.
