Rublev Colours Dispersion Pearl Pearlescent - 2 fl oz

Due to their inherent transparency, the colour of pearlescent pigments can be affected by the colour of the material over which they are applied. On a white background, the transmission colour can be seen at all angles, and the interference colour is not apparent. When it is on a black or dark substrate, the transmission colour is adsorbed by the substrate, and the interference colour is strong and bright at a specular angle. At the specular angle, the interference color is observed. At diffuse angles, the complementary colour of that interference colour is seen because the light is transmitted through the film.

Rublev Colours Aqueous Dispersions are pigments dispersed in water ready to be mixed with water-based mediums. These dispersions are especially made for use with traditional painting mediums, such as egg tempera, casein tempera, fresco, watercolours, and distemper (glue tempera). They are also ideally suited for use with gesso to make toned grounds for drawing and painting.

Pigment dispersions from Rublev Colours contain only naturally derived ingredients, pigment, and water, making them ideally suited for traditional mediums. Unlike other pigment dispersions typically made for acrylic mediums, Rublev Colours Aqueous Dispersions do not contain coalescent solvents, artificial dispersing resins, or other additives that interfere with natural mediums.

Aqueous Dispersions make preparing traditional mediums easy; you do not have to hassle with powders, grinding pigments in mediums, and calculating binder ratios to make water-based paint. They make adding the right amount of paint binder, such as egg yolk, is a no-brainer because the right amount of water is already contained in the dispersion; simply add egg yolk.
