First, the warmth and coldness of colors are also relative. Any two different colors put together will distinguish different cold and warm tendencies because of contrast. The same hue is also divided into cold and warm. If Beijing Studios compares scarlet to cinnabar, scarlet deceives the cold. Compared with purple, red is warmer. It is very important to divide complex colors into cold and warm opposing systems for observing, understanding and expressing the color relationship of objects. Just like the complex sketch relationship between darkness and darkness in sketch, this opposite relationship is interdependent.

Second, the law of cold and warm is a universal law, which plays an important role in the color relationship. Warm colors have the feeling of protruding, magnifying and spreading forward, while cool colors are the opposite. These laws are meaningful only when they are combined with concrete images in painting, so don't apply them mechanically with formulas. The two sides of an object are determined by the color of the light source, and the temperature of the light source determines the temperature of the bright color, and the hue presented is the sum of the inherent color and the light source color.

Third, the dark side is determined by the surrounding environment. The temperature of the ambient color determines the temperature of sleep. The color tone of sleep is determined by the purity of intrinsic color, the saturation of light source color and the strength of environmental color. The boundary between light and shade is the darkest part of an object, and its tendency to warm and cold is also the weakest. In fact, the boundary between light and shade is also the boundary between cold and warm. It contains both bright and dark colors, which is the sum of the opposite colors of light and dark. The highlight color is mainly the embodiment of the light source color. When an object is highlighted, the light color is mainly used to slightly enhance the color.
