Sepia is a brownish-gray color that resembles the ink made from the sepia cuttlefish. This ink was historically used by artists for drawing and painting, giving the color its name. The term "sepia" is often associated with vintage photographs, which have a warm, nostalgic tone. In addition to its artistic uses, sepia is also a term in biology, referring to the Sepia genus of cephalopods. These marine animals are known for their ability to change color and texture, providing camouflage in their natural habitats. The cuttlefish is a well-known member of this genus.
