First, the creation of oil paintings in the Impressionist style basically adopts the direct painting method, usually using white canvases as the main to obtain the strongest base for color, but there are also cream or light gray canvas bases depending on the color of the picture. The texture of the canvas should generally not be too fine, and the coarser texture can cause the loosening of the pigment color layer, which is not too rigid when the color is connected, and it is also conducive to dry painting. Except for a few painters such as Renoir and Laudrek, who liked to use the thin painting method, most typical Impressionists used thick painting and juxtaposed colors with different fine brushstrokes and colors, using pigments that were mostly opaque and translucent, and produced rich color contrast and fluttering effects through the method of color staggering overlap or juxtaposition.

Second, although the post-impressionist and neo-impressionist painters are fundamentally different from the traditional impressionists in concept, there are no fundamental differences in material and technical characteristics, but they emphasize subjective colors. The Neo-Impressionists separated the colors completely according to the principle of the seven colors of the spectrum, and even painted only with color dots in the basic colors of the unharmonized spectrum, so it was also called pointillism in the strict sense. However, there are still obvious differences in the brushes used by different painters, Monet's ease and freedom, Pissarro's roundness and age, Van Gogh's roughness and arrogance, and Seurat's rigor and caution.

Third, the impressionist painting steps have been well known, generally in the outdoor sketching is usually with thicker pigment slightly mixed directly to form a thick brush texture and produce color juxtaposition effect, because the scene sketching is mostly completed at one time, so basically based on wet painting, rarely add color medium dilution when necessary. In the production of oil painting or works that need to be carried out many times, it is necessary to pay attention to the order of first thin and then fat, generally first with turpentine color thinly spread out the base color, and then use thicker color to continue to deepen, you can also use dry painting method, with a brush brush to draw a covering color, so that the base color and the upper color form an intricate and colorful effect. Don't mix the pigments too hard, let the different colors naturally juxtapose, and visually mix to achieve stronger contrast. The treatment technique based on thick coating should also pay great attention to the thick and thin contrast, there must be a breathable place, can not blindly pile up the paint, otherwise the picture will appear cumbersome, but also cause oil absorption or cracking and other problems, for the part that is not ideal, or scrape off in time and wait for the dry to redraw as well.

Fourth, impressionist painting pays attention to the transformation and connection of the overall color rhythm of the picture, the smoothness of the charm, the loosening of the pen are very important, which is the same as the freehand style oil painting creation, if too much attention to details will appear rigid. Therefore, the treatment of the form should be boldly summarized, and efforts should be made to "get carried away", which is the characteristics and charm of color and pen.
