‘反衬’ is a literary and rhetorical device meaning 'to highlight something by contrasting it with its opposite.' The character 反 (fǎn) means 'opposite' or 'against,' while 衬 (chèn) means 'to set off' or 'to衬 (highlight through background or contrast).' Together, they describe the intentional use of an opposing element—such as color, behavior, or quality—to make a focal feature stand out more vividly. It’s commonly used in writing, art criticism, and descriptive speech to deepen emphasis.

This term appears frequently in classical and modern Chinese literature, film analysis, and nature writing—especially when describing how one animal’s timid behavior highlights another’s boldness, or how darkness intensifies the brightness of light. Unlike simple contrast (对比), 反衬 carries an artistic, purposeful intention: the contrasting element serves as a deliberate backdrop to enhance perception of the main subject.
