What is natural silk of golden color called?

Natural silk of golden color is commonly known as "wild silk" or "Tussah silk." This type of silk is produced by wild silkworms, primarily the Antheraea species, which feed on a variety of plants. The golden hue comes from the sericin and fibroin proteins in the silk, giving it a unique and luxurious appearance. It is often used in high-end textiles and garments.
