The brownish colour is due to the presence of Muga Gicha, Muga silk is a variety of wild silk geographically tagged to the state of Assam in India. The silk is known for its extreme durability and has a natural yellowish-golden tint with a shimmering, glossy texture. It was previously reserved for the use of royalty. Unlike other silks that require the pupa to be inside of the cocoon when degumming, Eri silk only uses the empty cocoons. The term 'Ahimsa' or 'Peace silk' or 'Non-violent silk' is derived due to this process.
