有一句歌词“我家住在黄土高坡”,民间亦有“脸朝黄土背朝天”的说法。人的生命融入土地后,最后的结局是剩下“一杯黄土”。由此可见,土地的主色调是黄色,在一般人的眼里,这种色彩带有单调和悲凉的味道。 There is a lyrics “My family lives in the high slope of the loess” and folks also say that “the face is facing the loess.” After people’s life is integrated into the land, the final outcome is “a cup of loess”. Thus, the main color of the land is yellow, and in the eyes of ordinary people, this color has a monotonous and sad taste.
