What are the decorative features of intermediate painted pottery in the late Majiayao culture in China?

Intermediate painted pottery also makes red and black colors appear on the same work at the same time, which makes the orange tire bottom present a more warm atmosphere. Usually red lines and black zigzag lines are used alternately to make the decoration more layered and three-dimensional. In addition, the intermediate painted pottery seems to notice that the pattern can get different visual effects from different angles, and consciously strengthen this effect, such as the "arc sawtooth painted pottery pot" (unearthed in Guanghe, Gansu Province), whose front looks like a calm water surface ripple, and looks like a concentric arc circle when viewed from the top, and there are ripples caused by stones in the water. The decoration of middle-level painted pottery is mostly dense, but attention should be paid to adjusting the decorative surface with parts of different sizes and shapes, so that people will not feel dull and depressed. The expression mode is either the theme pattern in the extremely fine net pattern or the three or four leaves in the leaf-shaped pattern separated by thick lines are empty and there is no decorative line, which makes people's vision rest. There are also various techniques such as decorating dense theme patterns in sparse geometric lines or appearing theme patterns in square continuous diamond squares.
