DETAILS



Chrome Yellow Medium is lead chromate, obtained synthetically as a yellow crystalline powder by precipitation from a solution of a lead salt. Chrome yellow light has good hiding power with bright yellow hue and high tinting strength. Chrome was discovered by the French chemist Nicolas Louis Vauquelin in late 1790 in the mineral crocoite (lead sulfochromate). Vauquelin studied the different chrome compounds and found he could obtain a wide range of colors from greenish-yellow to orange shades. A synthetic lead chromate (mainly chrome yellows) manufacturing process was published in 1809, although they were not mass produced until 1820 when the first large chrome deposits were discovered in North America.

NOTES



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.
