Introduction to Watercolor Painting: Overall Skills of Landscape Sketching
The so-called "global" refers to grasping the basic tone from shallow to deep (including the light-dark relationship and color tendency from shallow to deep), that is, first paving the brightest part of the light-receiving surface with light colors, leaving highlights, and then using light colors with a tendency of picture tone from bright to dark, that is, from highlight, bright part, sub-bright part, sub-dark part, dark part, and then from shallow to deep part, that is, sub-dark and dark part.
Another example is the color from light yellow, medium yellow, orange yellow, orange red, scarlet, purple, purple ..... until it is unified and rich, showing a harmonious and rhythmic relationship between color and light and shade. In this way, the general relationship of the picture is basically completed.
The so-called "color first, then shape" means to spread a big tone before drawing the outline of the appearance. This watercolor painting technique is to avoid focusing on the specific details of the physical structure from the beginning and dilute the observation and feeling of color. This needs to concentrate first, spread out the most prominent color feeling in an all-round way with the most decisive brushwork, and grasp the subtle color effect instantly. Then, under the unity of hue and rhythm, the physical structure and image characteristics of the main scenery are described in detail, and finally completed by adjustment.
This watercolor painting technique is based on the requirements of the painter's accumulated experience, flexible adaptability and ability to control color changes, as well as the foresight of the deep effect and difficulty of the picture.
