Rublev Colours Lithopone is an organically-coated white pigment based on the co‑precipitated compound of barium sulfate and zinc sulfide. It is a semi-transparent white almost equal to zinc oxide in whiteness and holds a medium position in density between lead white and zinc oxide. The zinc sulfide content is 30% by weight, whereas, on a molecular basis, lithopone consists of the two components at a ratio of 1:1. The zinc sulfide does not have the same issues in oil paint as does zinc oxide (zinc white).

Some separation of pigment and oil may occur in Rublev Colours Artist Oils, and it is a natural process when no wax or stabilizers are added to the paint to prevent it.
All color swatches on this website are 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 due to the wide variance among color monitors.
Color Swatch Note: The color swatch was created with a thick application of color (left side) and a tint (right side) made with equal parts of color and titanium white, applied to acrylic-primed cotton canvas.
Drawdown Note: The image of the “drawdown” shows a premixed paint film 6 mils (0.006 inches) thick, 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 with titanium white at a 1:2 ratio, on the right. The bottom area of the drawdowns is scraped to show undertones.
