Required tools and materials: 1. Paintbrush. Special watercolor brushes generally come in two types: flat heads and round heads. Most watercolor brushes are made of natural and synthetic materials, and there are also expensive mink hair brushes. However, for ordinary watercolor painting enthusiasts, ordinary brushes are enough. To engage in general sketching or creation, you need to prepare large and medium-sized brushes. , small three types of round-headed paintbrushes, a board brush about three to four centimeters wide and one or two flat-headed paintbrushes. 2. Drawing paper. For painting paper, you can choose cold-pressed watercolor paper. The surface particles of watercolor paper vary in thickness. Which one you choose depends on the artist’s personal habits, picture content, frame size and other factors. For beginners, the appropriate frame size is generally not required. It should be less than 20cm*30cm and no larger than 40cm*50cm. The ratio of length and width depends on the interest and subject matter. Before painting, it is best to wet both sides of the drawing paper with clean water, and then use water-melting tape to stick the drawing paper to the drawing board along the four sides of the paper. After drying, the paper surface will be very smooth, and the paper surface will also become smooth during the painting process. There won't be much deformation. 3. Paints and palette boxes. There are many types of watercolor paints, but it is generally impossible to use all colors when painting. In fact, there are only seven or eight kinds of paints that are commonly used. Generally, everyone has his own painting habits. For the convenience of color mixing, the colors are generally arranged in order according to the cold and warm categories. The commonly used colors are: deep red, bright red, vermilion, orange, earthy yellow, medium yellow, lemon yellow, permanent light green, emerald green, lake blue, and ultramarine. , Plain Blue, Patrón Grey, Van Dyke Brown, Ripe Brown, Ripe Ocher. 4. Auxiliary tools. Such as a water bottle for brush pens, a small bottle with a spray nozzle or a paper towel, etc. In addition, sponges are also commonly used tools for cleaning and modifying pictures. Painting techniques: dry painting. Dry painting is a multi-layered painting method. Use the method of layer coating to color the dry background without seeking a bleeding effect. You can color it over and over more calmly. It is easier to master and suitable for beginners to practice. ① Layer coating: That is, dry overlapping, and then paint after the coloring is dry. The overlapping colors express the object layer by layer. The number of layers of color varies in the picture. Some areas require just one, while others require two, three or a little. However, it is not advisable to paint too many layers to avoid the color becoming gray and losing its transparency. The layers of paint are like colored overlapping, and the mixing effect of the base color is expected to be revealed in advance, which cannot be ignored. ② Color masking: In fact, it is also a dry overlapping method. The color masking area is larger. For example, if the colors of several areas in the picture are not uniform enough, you have to use the color masking method to mask the color once to make it uniform. If a certain color is too warm, cover it with a layer of cold color to change its warm and cold properties. The color to be covered should be applied in a thin layer with a brighter color, and it should be spread over once. Generally, do not touch back, otherwise the background color will be brought up and the color will be smudged. This method is often used during the coloring process and when adjusting the picture at the end. ③Color joining: Dry color joining is to paint the adjacent color from the side after it dries. The color blocks will not bleed. Each color block itself can also be painted wet to increase the variation. This method is characterized by clear outlines of objects and bright colors. ④Dry pen: The tip of the pen has less water and more color, and the brush is prone to whitening; using relatively full water to draw quickly on rough-grained paper will also cause whitening. The dry brush method is often used to express effects such as sparkle or softness but firmness.
