Textile dyer Sachio Yoshioka is a throwback in the best possible way. While 99 percent of fabrics these days are dyed with hard-to-pronounce chemicals like azophloxin, chrysoidine R and xylene cyanol FF that are bad for the environment, Kyoto-based Yoshioka creates bright, colourful dyes using locally-sourced plants—like saffron and pampas grass—and traditional techniques that date back to the Edo period.
