Lukas oil paints are high-quality paints from Germany that have a long history of use by both student and professional artists. The oil paints from this company come in a range of transparent colors for washes and detail work and in a range of opaque colors that can mix with transparent colors to provide a variety of new tones. Transparent oil paint colors are colors that are easy to thin to an almost see-through consistency. They are not transparent in the way that glass is, but they are less dense compared to other oil colors.
Transparent oil paints are ideal for mixing, glazing, and adding new color tones to an existing image. Some painters use transparent colors on top of existing colors to add depth to a painting or to bring it together. Experimenting with transparent colors adds a new dimension to your painting.
Transparent earth colors are used for warm glazing effects. As the name indicates, they often originate from the soil, sometimes from a special locale. Gold ocher is a warm, yellow earth color that imparts a lovely mustard hue. Asphaltum is a color that used to be impermanent but is now created in a new way. It has a charcoal hue and is good for toning down brilliant areas or unifying a region of a painting such as a stormy sky. Transparent mars colors are made synthetically from elements and come in a range of hues.
Phthalo colors, derived from copper phthalocyanine(C32H16CuN8, the same name as CuPc or Phthalocyanine blue), come in more or less a continuum of hues ranging from sharp green to intense blue. While transparent, they are powerful pigments and a little goes a long way. Different companies make slightly different varieties of the shades. The basic phthalo blue and phthalo green tend to look rather electric and synthetic. They mix well with zinc white to produce very lively tints. They can be used for glazing as well but won’t yield the warm or subtle color that is often desired from the glazing technique.
The oil composition varies somewhat from paint company to paint company. Some pigments are made from plants, while others are made of rock material. In some instances, minerals are dyed to create pigments. Plain, mineral-based pigments such as titanium create opaque colors that are hard to see through. Pigments made from minerals with dye added or plant material tend to create transparent colors that make excellent glazes. To create an opaque color, mix a transparent color with an opaque color that has a mineral base.
