          The main painting skills are:

           ① transparent color cover law, that is not used only by the white color of oil paint diluted to carry out multi-level portrayed. Each layer must be dry after the next layer of color, because of the color of each thinner than the middle and lower levels of color can reveal subtle, and the color of the upper formation of subtle changes in the color. For example, in the dark red color painted on the floor of the stable blue cover, it will have a blue-purple that is thoroughly in cold Yu in the warm rich results, which often can not be out on the palette of colors. This oil painting images suitable for the performance of the solid sense of texture and, in particular, can be vivid picture of a figure delicate skin color changes in the skin is a flow of blood under the skin. On the down side, a narrow gamut, making the process works fine, to complete the works long hours and difficult to express in real-time painter's emotional and artistic creation.

  ② opaque color Review Act, also known as multi-level shading. When the first monochrome

oil painting drew large physical appearance, color and then create a multi-level, the Department often painting a dark thin, light and the tone in the middle is the Department of thick layers of painted or covered or left to form a color contrast. Due to varying thickness, showing the rich color and texture intended to rhyme. And both transparent and opaque painting is no strict distinction between the artist often works in a comprehensive use. Performance in the dark or in the shadow of the object, with a transparent cover color can be produced stability, deep sense of the size and sense of space; review opaque color easy-to-rule in the dark shape of the body other than the Department to increase the screen color saturation. The painters of the 19th century before most of both painting, produced works in general a longer period of time, and some Huawan after a long-term placement, the color layer to be completely dry and then painted to carry out.
