The two-line sketching and coloring technique, as a painting method, can be traced back to the ancient Chinese painting art. This technique emphasizes outlining the basic contours of objects with simple lines first and then gradually adding colors and details to make the picture more vivid and three-dimensional.

In ancient China, painting was considered an art form for cultivating one's moral character, and the two-line sketching and coloring technique was one of the most representative painting techniques. It can be traced back to the silk paintings of the Warring States period, when painters began to outline the contours of figures and landscapes using simple lines. Over time, this technique continued to evolve and develop, finding widespread application in the painting works of the Tang, Song, and other dynasties.

The characteristic of the two-line sketching and coloring technique lies in its emphasis on the fluency and rhythmic quality of lines. Through variations in the thickness, darkness, and speed of lines, it expresses the form, texture, and movement of objects. At the same time, this method also emphasizes the use of color, utilizing contrast, harmony, and transitions to enrich the picture, providing the viewer with a strong visual experience.

In modern painting, the two-line sketching and coloring technique is still widely used. Many painters adopt this technique to express the layered and three-dimensional qualities of their paintings. Simultaneously, with the advancement of technology and the continuous updating of modern painting materials, the two-line sketching and coloring technique has also undergone new developments and innovations.
