Compared with the techniques of oil painting and gouache painting, the most prominent feature of watercolor technique is the method of "leaving blank". Some light and white parts need to be "left blank" when drawing dark colors. The transparency of watercolor pigments determines this painting technique. Light color cannot cover dark color, unlike gouache and oil painting, which can be covered with light color and white powder.
Proper and accurate blank or light color will enhance the vividness and expressiveness of the picture; On the other hand, improper blank space will easily lead to trivial and messy pictures. Mark the blank with a pencil before coloring. When coloring, you should skillfully omit the key details, that is, dots and faces.
In addition, where the contrast colors are adjacent, the other side should be empty and colored separately to maintain their uniqueness. Some beginners leave unnecessary empty shapes and then paint colors along the outline. Some people leave empty places dead, too rigid, and lose vitality along the outline.
However, watercolor blank glue can also be used, and the parts treated with blank glue must be dried before repainting. Once dried, these areas will still be protected from pigment infiltration, which is also a good way to "leave blank". Of course, emptiness is accurate and vivid, which is the embodiment of skill. Repeated practice in practice makes perfect.
