Why is the colour yellow knowed for cowards?

The association of the color yellow with cowardice has roots in various cultural and historical contexts. One reason is its use in literature and folklore, where characters displaying cowardice are often depicted with yellow imagery. Additionally, the term "yellow-bellied" has emerged in English vernacular to denote someone who is fearful or cowardly. This symbolism may also stem from the color's connotations of caution and hesitation, reinforcing its link to timidity.
