(1) objectivity
The objectivity of the main melody film color is its most basic feature. The most important thing of film color is to imitate and copy objective things and show the true color form of objective things. This is the primary purpose, and the second step is to play an artistic role in expressing emotions and transforming the environment. As far as theme movies are concerned, the reproduction of real historical scenes and the restoration of historical facts are the artistic attitudes that every creator should follow. If the color of a main melody movie is divorced from the real historical color, the audience's viewing effect will be quite dramatic, and they can't better enter the scene experience brought by a movie. Suppose a film uses objective expression techniques to make the color rhythm and plot narrative of the film complement each other, and then present the most perfect audio-visual feast for the audience.
Narrative part
After fully realizing the objectivity of the color of the main melody film, narrative is its promotion expression. Color not only depicts the objective image of nature, but more importantly, it is also a narrative modeling factor that cannot be ignored. The producers of main melody movies give full play to the artistic symbols of film color to present the most perfect visual picture for the audience, and then stimulate the hidden life feelings of the audience. Create an atmosphere that is completely in line with the story and real life. Even if the film is a fictional story, the film color has transformed it into a beautiful story that the audience is convinced. This is the so-called film color narrative method.
(3) Technology
Technicality is an indispensable feature of modern film color. Compared with the early film color, it is mainly based on the application of chemical principles such as film sensitization and printing to achieve the picture effect. Modern movies are more closely related to the development of science and technology. Modern movies rely more on the color rendering in the later stage of movies, and the color production in the later stage of movies on the market is also more sophisticated. Many main melody films have also begun to pay attention to the use of modern media technology to render the color of the film, which greatly improves the appreciation of the film.
