Why is red considered the color of love?

According to one version, love began to be associated with the red color after the appearance of a popular French poem of the XIII century called “The Novel about the Rose”. It talks about the hero’s allegorical search for a red rose, which symbolized his beloved. And later, in the XIX century, French and English writers created a language of flowers, according to which a red rose means love. Subsequently, not only the red rose was associated with love, but also the color itself.

But for some time in the Middle Ages, the green color was often associated with love and other natural desires of a person.
