Steps of classical overdyeing technique for oil painting.

1. Drafting and finalizing

There are two ways to draft, one is to draft directly on the canvas base; the other is to draft by transferring. After the draft is finished, it is finalized with ink. Dilute the Chinese ink with a small amount of water, and use a pointed brush or a small pen dipped in ink to outline according to the charcoal strip draft, so as to make the picture image more clear and fixed.

2. Overdyeing the base color and whitening

Blend the earth red oil paint with a medium, and brush it onto the canvas with a wide brush, and the amount of paint should be moderate. While the earth red is not dry, use the emulsion to make white color, use the wider brush to start from the lighted part of the image, and paint the bright part with white color effect. Painting should forget the status quo, only the relationship between the light and dark light and shadow of the form, you can only according to the light of the direction of the line of the pen, as shown in the figure below.

3, cover color

To the last step of the paint dry, depending on the needs of the picture, with a large amount of absorbent soft brush, dipped in media agent transparent solid color on the form of cover dye. The first color overdye to be bold, unrestrained, flexibility is also greater, can be covered with the same tone, can also be divided into bright, dark and background with different colors overdye, can also be bright overdye, followed by the deployment of the form of color is closer to the color but the more chalky color painting the dark, so that overdyeing and painting combined, as shown in the figure below.

4, in-depth carving

With a soft brush and then thinly brushed once the medium, followed by the emulsion white again will be brightened by the light part. Slowly into the details of the painting, the dark portrayal of the same time to follow up, to be the color layer is dry and then cover dye. This process is to let the whitening and overdyed repeatedly alternated, gradually shrinking the scope of the whitening. The process of deep painting is composed of two closely integrated steps alternately, white is the shape of the modeling, so that the modeling is further clear, more vivid and evocative; cover dyeing to make the image of the rich colors, as shown in the figure below.

5, the final painting

The bright part of the white area has shrunk to a very small, may only be left in the highlights, then do not use pure white and use the emulsion tone lighter powder and the object is closer to the color of the color of the direct painting of these small localities, to be dry and then cover the dye is complete, as shown in the figure below.

Starting skills

1, charcoal sticks. Both charcoal essence sticks and charcoal strips are suitable for sketching on canvas or board. Charcoal sticks are better because they leave lighter marks, are easier to erase, and are more flexible to use. The charcoal essence stick leaves a very heavy line, making the contour lines more defined.

2. Charcoal pencil. Thin lines, more suitable for drawing fine details. Some people do not advocate the use of pencil, that lead marks will come up from underneath the oil painting color layer.

3, color chalk and crayon. It is not easy to use too much on the canvas, to avoid the use of white or light colors. Excessive use of color pencils or crayons in this kind of sketching will make the base unstable.

4. Watercolor and acrylic colors. Very thin watercolors will not have any effect on the coverage of oil colors. For thicker coverage, use acrylic colors.

5, water ink. It is interesting to use Chinese ink for calligraphy and painting. The ink line can either be covered with an oil color or retained; it won't wash out easily with turpentine.

6. Copy paper. A sketch on paper can be copied onto canvas. In the stage of starting the sketch, hairspray, glue and other fixing fluids are indispensable. It is necessary to spray a layer of fixing liquid for the material that is easy to fall off or flood color. In addition, a variety of erasers, rags, etc. is also a necessity.
