In booth design construction, the color tone changes are quite diverse. In summary, they are mainly influenced by the following factors:

1. Light source: The same object will appear in warm tones under warm light. If it is illuminated by cool light, it will appear in a cool tone. When the light carries a specific color, the entire object will be unified within that hue, just like on a theatrical stage. Different colors of lighting affect the stage tone.

2. Inherent color: The inherent color of an object is the fundamental factor determining its tone and plays a very important role. For example, in spring, the mountains and forests show green tones; in autumn, golden tones; and in winter, gray-brown tones. These changes mainly depend on the inherent color of the object itself. What we often refer to as a painting is green, purple, yellow, and blue—referring to the inherent colors that make up the object in the painting. It is precisely these dominant colors that determine the tone of the painting.

3. High and low tones: This mainly refers to the contrast between brightness and brightness of colors in a color tone. When designing and conceiving color tones, blue tones can be divided into high and low tones, and cool tones can also be high or low. High-key colors have high brightness but weaker brightness contrasts, characterized by lightness, elegance, and brightness. Low-key colors use dense, rich, and low brightness, with stronger contrasts between light and dark. Their characteristics are deep, solid, and varied. Different pairs of light and dark colors can create rich tonal variations.
