Story
Our story began at a Buyi cultural festival in Guizhou in 2017. Seeing indigo color transfer during wear led Woody Long to study dyeing process control. In 2026, Green Cosmos began coffee-dye trials on cotton, wool, silk and yak hide, exploring Yunnan coffee grounds and fruit skins. Today we develop plant-based garment dyeing, custom colors and botanical prints, from 100 pieces per color.
