Mars Crimson is dark bluish red oil color that makes cold red tints. Originally a brand name in the late 18th century, Mars colors is now the common name for synthetic iron oxide pigments. Their chemical and physical properties are similar to the natural iron oxides. Mars colors are permanent pigments with good tinting strength and are good driers for oil paints.
Mars Crimson is the bluest synthetic red iron oxide pigment we could find. We grind it in pale refined linseed oil with a small amount of bodied linseed oil to prevent it from becoming matte upon drying. The bodied oil, however, gives it some tackiness and drag under the brush. This can be easily remedied by adding a small amount of linseed oil or Oleogel to the paint on your palette.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 are scraped to show undertones.
