The classification of oil paints

will be improved, but not with chrome yellow color blending with sulfur, dark black is easily adjusted. Chrome yellow and white lead can not allocate more now on the market have been rare chrome yellow cadmium yellow cadmium sulfide is the chemical composition. The painting color is yellow cadmium yellow, the light is very good, can not change color durable, non-toxic, very stable, did slow addition to the yellow, the color of light yellow oil, deep yellow, or orange color is cadmium sulfide mixed with other color pigments, these are very stable color. there is a cadmium lemon Huang, stability is much better than lemon, but the color is weak in direct sunlight will become the next orange cadmium yellow cover strong force, almost all of the paint and to reconcile the use of copper paints are less common response, tend to darken the reconciliation, to reconcile with the chrome green, dry color will deepen. Naturals is a mineral pigment, a natural iron-containing compounds can be synthesized. Made of gold yellowish brown, yellowish brown two kinds. Production abroad there is light yellowish brown and dark yellowish brown, the yellow color in the stability of the best, there is a strong color strength and coverage, dry layer of solid color, any color can be mixed. chrome yellow, cadmium yellow, Sardinia the stability are not good enough, Permanent Yellow made more stable alternative to other uses yellow addition, cobalt is a bright transparent yellow color, more stable, but make it difficult, and difficult to blending with ultramarine, domestic production .

Red Class
Red type, commonly used vermilion, cadmium red, carmine, rose red, red soil that is red cinnabar, mercuric sulfide, the chemical composition, slightly toxic. Made of cinnabar stable quality is excellent pigment. Oil red paint done slowly, strong coverage, more durable alone, but direct sunlight will darken. Use red when the ancient masters, or coated with a transparent layer of wax to protect the color, red and copper tend to darken the color of harmony, and proportion of the lighter color (such as Prussian blue) will be to reconcile the phenomenon of Pan-color. Cadmium sulfate cadmium red and cadmium serenade, alternative cinnabar, can be made into red, dark red, purple and other colors. Cadmium red, bright, thick split, with good coverage ability, long drying time, sun exposure will gradually darken, cadmium yellow and cadmium red can be deployed into the orange, the color of copper avoid and reconcile, in addition to reconcile with any color and durability does not change color. Western carmine red that is extracted from the cochineal color, non-toxic, very bright beautiful, but less stable, whether direct or scattered all fade. Rose madder red in the past is the root from the plant extract. Now the red rose plant is a synthetic alizarin red, relatively stable, long drying time, thickness of coating can not be used alone, is too thick and easy darker color, tone was thin dry easily fade. Red pigments are mineral soil, has good stability and strong coverage ability, after a relatively dry solid. Poor quality of the soil red, dry and easy to crack. The proportion of all the roots is less toner, and a relatively high color blending, color is often easy to pan. Painting in the use of red color process, generally can not be stressed too thick or too thin. European old masters and is now using the red pigment is different. Red ash and clay artists often use, they are stable and strong, but the color is not bright. Pink iron (iron oxide) is now only using it as a painter background. Fast Red is a coal tar lake pigments, similar to the red, bright color, more stable.

Blue, green class
Blue, green classes are common ultramarine, cobalt blue, sky blue, Prussian blue, Chin Lin, gem green, green, chromium green, cobalt green, earth green, light green and ultramarine: the first is a natural semi-precious stones (jade bluestone) grinding made it crystal clear with beautiful color, very expensive. Today, using a synthetic ultramarine, strong stability, poor adhesion, coverage ability in general, done slowly, for transparent painting. In addition to copper color (green gem) a slight reaction, the can reconcile any other pigment. Produced by ultramarine violet, ultramarine, and has the same performance. Cobalt blue (cobalt): the blue color in the stability of the best coverage and dryness of the medium, for transparent painting, works best alone. Never in the dry color layer without the use of tone too thick, easy to dry. Cobalt violet and cobalt blue of the same characteristics, the nature of the pigments belong to the same class. Sky blue: cobalt blue with close colors, have certain stability, micro strip green, bright, clean but compact. Durable, easy to dry. Prussian blue, also known as Paris Blue, iron and cyanide compounds, strong tinting strength. Stable, well done faster. With white lead, cadmium colors, red soil to reconcile, will play oxidation, long brown hair will cause the screen. Chin Lin: arsenate color stability in general, poor light, easy to fade. Green gem: stability, weak coverage, color crystal clear, is a lighter weight transparent color can be used for transparent painting. Emerald green, also known as green: the color rich, green color of the most stable, done slowly. Chromium Green: good coverage, dry slowly, excellent stability, and cadmium yellow to reconcile a response. Cobalt Green: covering force general, done quickly, with a variety of color harmony, better stability. Green earth: a brown soil with paint, easier to dry, has good coverage ability, but not very bright warm colors, can be reconciled with any paint, very stable. Light green: from the natural mineral extracted iron from the development, there is good coverage ability, can be reconciled with any color, more stable.

Brown, black type
Ocher: is derived from iron ore, excellent stability, yellow ocher and red ocher points, is the most common color of ancient artists, strong coverage, dry, and solid. Now on the market are mostly synthetic ocher, ocher than the natural transparent, high strength and durability. Cooked raw sienna and ocher that contain iron and manganese compounds made of colors, ripe reddish color in the water more stable, less stable in the painting in color, in particular, not be stressed too thick. Cooked raw ocher ocher's worse than some of the stability of these two colors is not too good coverage ability. Raw and cooked brown: the color of these two pigments are dim, are the natural soil pigments. Students tend to brown with a touch of green, cooked brown reddish tendencies, old course of time preference will be stronger. The proportion of cooked brown lighter, easier to come from the color layer in pan. The two-color painting done quickly, with other colors mixed dry faster, when used alone should not color it does not dry before painting another layer of color, or dry the screen easy to crack. That is when the base oil with it, must dry before you can use, and alone can not be stressed too thick. Because of its lighter weight, classical painters often use it to transparent painting, in coal tar and asphalt in the extraction of brown pigments, because the material contains impurities, stability is poor. If the varnish on the screen to reconcile transparent method of painting, can be used to copy the European classical works. Ivory Black: Are the animal bones in the absence of air under the conditions of roasting from bone black. Oil well as color stability, easy to dry cracking is the most pure black pigment. It is adjustable and the use of any paint is China's current production of black pigment in the best varieties, when used alone the possibility of cracks. Only a little bit the other pigments to reconcile cracks can be avoided. Coal Black: It is produced from the soot in the paint. With cold colors, good stability, done slowly, adjustable, and a variety of pigments used.
