How can you draw a relationship by sketching black, white and gray?

First of all, pay attention to the overall relationship.

The relationship between black, white and gray: that is, the three color blocks of black, white and gray in the picture have great color difference, but it is difficult to locate them because any color block is relative in the picture. For example, the phrase "the picture is too gray" often mentioned by teachers has a clear meaning.

The relationship between black, white and gray is the overall tone of the picture in sketch, and it is the modeling element that constitutes the basic relationship between black and white pictures. A successful sketch must be accurate in shape, natural in light and shade, prominent in theme and complete in overall relationship, so as to have artistic appeal.

Observation method:

1. Observe whether the bright part in the picture accounts for at least 3/ 1 of the picture.

2. The dark side should have only one heaviest place and should not appear in the existence of multiple points.

3. The gray surface is an intermediate color between the dark surface and the bright surface, and whether the distinction between the gray surface and the bright surface is clear.

Extended data:

To grasp the relationship between black, white and gray and achieve the best effect of treatment, we must first start with observation. From a useless point of view, the change of light and shade and the treatment of black, white and gray are unnecessary, but generally we will encounter two situations in painting.

The first is the contrast change of light and shade caused by sunlight on the object, and the second is the contrast change of light and shade of the object handled by the author himself.

Sketch is different from color. In the creation, we should abandon the color of the object itself, because the changes of different colors of the object are represented by black, white and gray, and we must deal with the erotic blocks to rationalize the changes and progression of the color blocks.
