    Rublev Colours Ultramarine Blue (Green Shade) is made using the greenest shade of ultramarine blue pigment we know. Ultramarine blue a synthetic inorganic blue pigment consisting of a double silicate of aluminum and sodium with sulfide and occurs in nature as a component of the semi-precious stone, lapis lazuli. Processes to make the artificial pigment were devised by Jean Baptiste Guimet (1826) and by Christian Gmelin (1828); but while Guimet kept his process a secret, Gmelin published his and thus became the inventor of "artificial ultramarine."

    Rublev Colours Watercolors are made with the same pigments used by watercolor masters of the 17th to 19th centuries.

    We make Rublev Colours Watercolors in small batches using gum arabic and sugar syrup, which were the basic ingredients in watercolors of past centuries. There are no other additives to alter the characteristics of each color.

    Rublev Colours Watercolors do not contain fillers to extend colors, dispersants to disperse and granulate pigments and brighteners to intensify colors. Rather, each color is crafted to develop its unique character so they behave much the same as the colors of past masters.

    We use gum from Acacia trees and clarify it with activated charcoal to make a pale gum arabic solution.

    Honey and sugar syrup were used throughout history as an ingredient in water-based paint to prevent it from drying quickly. Colors made with these ingredients do not dry quickly and are easier to dilute.

    Available Forms

    The range of Rublev Colours Watercolors is available in 15ml aluminum collapsible tubes of paste colors, and 3 ml full- and 1.5 ml half-pans of semi-moist cakes.

    Properties Permanence

    Most Rublev Colours Watercolors are rated I or II, according to ASTM lightfastness standard, showing little or no change in watercolors. Those of lightfastness III category may be sufficiently lightfast if they are provided with extra protection from UV light.


    Staining is the characteristic that makes color difficult to remove from paper after it has been applied. Less staining colors can be lightened or removed almost entirely when wet or when rewetted and then lifted with a clean, wet brush and blotted up with a paper towel. Staining depends in large part on the paper and the particle size of the pigment. Staining is increased by the use of dispersants, because they act to embed pigment particles in the fibers of paper, dulling the finished color. While most brands of watercolors contain dispersants, Rublev Colours Watercolors do not; so staining is minimized.


    Granulation is the appearance of visible pigment particles in the applied color, especially when the paint is diluted and applied with a wet brush.


    Flocculation is the clumping together of pigment particles, typical of some colors, such as ultramarine. Both granulation and flocculation create subtle effects as the paint dries and are considered desirable by accomplished watercolorists. The trend in commercial watercolors is to suppress pigment textures in favor of homogeneous washes of color. Many of the pigments used in Rublev Colours Watercolors are composed of large particles and produce granulation effects naturally without the use of additives.


    Rublev Colours Watercolors are composed of ingredients that are not considered toxic—ingredients that are often found in food and cosmetics. There are no hazardous solvents or additives.
