Rublev Colours Natural Black Oxide is deep black with high tinting strength, opaque and brushes long. This mineral black is from the last remaining European companies operating the ochre deposits in the French quarries in the heart of the Luberon Massif. A dense, opaque color that is absolutely permanent, black oxide is a natural mineral iron oxide. It is comparatively neutral in undertone and is non-greasy when compared to carbon blacks. It is a useful color when these qualities are required.Composition and Permanence

Some 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 in this web site are only approximations of the actual color of the oil paint. We have taken every care to match the color in these pictures on calibrated color monitors to the actual color. However, because of the wide variance in color monitors the results you get may vary.
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 mil (0.006 inch) thickness applied to a standard test card for the purposes of examining color consistency, opacity and other qualities. The drawdowns show the color full 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.
