Why are the colors of Japanese movies always gray?

Japan's unique geographical environment makes the nation sad. People appreciate cherry blossoms not only because of their beauty, but also because of their fleeting fading.

The dark environment makes the indoor space full of Zen. People take sadness as beauty and love hazy aesthetics.

Most Japanese films follow the traditional photography techniques, using film, natural exposure and no need for supplementary light, which is very different from many of our film shooting concepts. The same movie is basically the same before the original film is dimmed and toned. Most of our films are processed by post-dimming technology, but many Japanese films still follow the traditional concept of no post-processing to retain the texture of the original photography. Movable images of movies are used to create cameras that take moving pictures with actual scenes, using traditional drawing or micro-animation technology, with the help of CGI and computer animation, or through some or all of these technologies, and other visual effects.
