While the concept of "pure love" is abstract and can be interpreted in various ways, pink is often associated with it. Pink flowers, for example, symbolize innocent and perfect love. The deeper the pink, the more intense the message of love. However, it's essential to remember that color associations are culturally influenced and can vary.
For example, red is often associated with passionate love, and purple represents eternal love. Ultimately, the color of "pure love" is subjective and depends on individual interpretation and cultural context.
