What do cover dyeing, sub dyeing and rendering mean in Chinese painting?

Secondary dyeing: it is a fine local dyeing with transparent watercolor or light ink, which gradually transitions from deep to shallow, so many times, the spatial level and tone change of the object image are dyed.

Dyeing: refers to the connection between water and color, or between colors. After a color is painted, the first color is blurred with a pen or a colored pen when it is wet, which is a natural transition and very interesting.

Contact dyeing refers to two pens dipped in different colors and dyed from different directions. When they touch each other in the middle, the colors naturally blend on the paper. This method should be done once, not repeated many times, so as not to fade. That's how Chen Zhifo drew branches.

Cover dyeing: also known as general dyeing, it is a large area of color cover dyeing on the basis of separate dyeing and receiving dyeing, so that rich and complex colors are harmonious and unified. Under normal circumstances, the cover dyeing adopts transparent plant color, and the pen should be light and even when dyeing, so as to avoid repeated smearing on the picture.

Embedding: brush strokes are used instead of rendering, which is mostly used to express the texture or weight of rocks. When using brush strokes, brush strokes should not be too exposed. Pay attention to the gradual change of brush strokes, and then compare them after the brush strokes, so that the brush strokes and brush strokes are integrated, which is not only interesting in texture but also harmonious with bone lines.

Spot dyeing: it is a common dyeing method in freehand brushwork, including dry dyeing and wet dyeing.
