For the browns, I mix Rublev Colours Transparent Red Iron Oxide with phthalocyanine green in varying proportions. With Mars colors, that might well be possible.) Mars brown is more opaque than umbers and siennas.įortunately, Rublev Colours also has transparent red and yellow iron oxides, from which a wide range of dark, transparent browns and greens can be made by adding very small amounts of phthalocyanine green to them. It’s important to me that none of the colors in my painting will fade or change in any significant way for centuries (or ever, if that can be achieved. These are the most lightfast pigments in existence. Mars brown, an iron oxide pigment, is as lightfast as any natural earth pigments, including burnt sienna. Its high tinting strength means that if used primarily in mixtures, rather than alone, one tube of Rublev Colours Mars Brown will last a very long time. Mixed with green, it can take the place of raw umber. Mixed with bone black, it can substitute for burnt umber quite satisfactorily. With Mars brown on my palette, the absence of umbers is no great handicap. I have eliminated umbers from my palette for reasons explained in my book, which I won’t bother to go into here because this is about Rublev Colours’ Mars Brown, Transparent Red Iron Oxide, Transparent Yellow Iron Oxide, and Chromium Oxide Green. The white I use for underpainting is Rublev Lead White #1, which begins to set up in 6–8 hours and perfectly suits my painting ways. Its high tinting strength makes it one of the ideal paints for tinting lead white for underpainting because so little of it needs to be added to lead white to create a range of values, thus allowing the underpainting’s primary ingredient to be lead white, which is the most perfectly suited paint for the underpainting of all oil paints in existence for its fast drying, its high pigment volume concentration, its superior film strength, and for the beneficial effects it imparts to all the paints in the ensemble. ![]() ![]() Mars brown is one of the paints listed in William Bouguereau’s notebooks, and it appears in mixtures with white in the flesh tones in his paintings of light-complected people, for which he is widely renowned among artists. As Natural Pigments adds more of the colors I need to their Rublev Colours line of oil paints, I will retire those colors I have from other brands and replace them with Rublev Colours. My preference is for oil paints with no stabilizers in them, just linseed oil and pigment, and I know of no other brand that meets those criteria. As a realist painter of long-standing, I’m very happy to now be able to add Mars Brown, Transparent Red Iron Oxide, Transparent Yellow Iron Oxide, and Chromium Oxide Green from Rublev Colours to my Number One Paintbox and my palette.
