📜 Origin & History

Seashell is one of the classic colors in the X11 color system named after natural objects. Its color inspiration comes from the pearlescent white glow with subtle pink undertones found on the inner wall of seashells.

Since ancient times, shells have played important roles in various civilizations. Ancient Romans used shells to make vessels and ornaments, while ancient Chinese used them as currency. The soft color of the shell's inner wall has left a deep impression on human aesthetics.

In Victorian England, shell craft collecting was popular. Aristocratic women collected shells during seaside holidays and made decorative pictures, making Seashell a fashionable color in interior decoration at the time.

20th-century advances in marine biology revealed the secrets of shell color. The nacreous layer on the inner wall is formed by alternating layers of calcium carbonate crystals and organic matter, a microstructure that creates the shell's characteristic warm luster.

The modern beauty industry draws inspiration from seashell color, developing cosmetic lines with a pearlescent shell-like sheen. Seashell has become an important reference color for natural nude makeup and luminous base products.
