Among the heroes, Zhang Yimou used several colors to represent four versions of the plot.

Four colors. Among them, black is mainly the hue of the unknown and the king of Qin, which runs through the film and symbolizes the style of the Iron Age, the majesty of Qin and the cruelty of history. On the one hand, red reflects the description of love desire, on the other hand, it symbolizes the blood of historical rise and fall, and emotionally reflects the director's allusion to cultural blood. "Green" depicts a world full of fairy tales, embodies the characters' detachment from the secular world, and contains the reverence of the king of Qin for chivalrous, righteous and brave people. White represents purity, essence and unity, showing the real world of movies. The story structure of this film is relatively simple, and the use of color and artistic modeling are also quite good, making the picture as perfect as possible. Through the sword, guqin, calligraphy, Go and other Chinese elements, this is an excellent patriotic film, and the heroic dream in the film also contains the desire for modern peace. The biggest feature of the film is color segmentation narrative. In stylized narration, Zhang Yimou always uses the element of "color" to divide stories with different themes, which accords with the characteristics of restrained and freehand brushwork in China culture. Zhang Yimou's color art has been brought into full play in this film. Color not only promotes the development of the story, but also implies the emotions of the characters.
