In Western cultures, Seashell often symbolizes purity and innocence, making it a favored choice for weddings and nurseries. Conversely, in some Eastern traditions, it can represent tranquility and peace, reflecting the calming presence of the sea.
The term 'seashell' dates back to the 17th century, referring to the shells of marine mollusks, which have been used in decorative arts since ancient civilizations. The color itself gained popularity in the 20th century as pastel shades became a staple in interior design and fashion.
