In episode 53, our first episode of Season 2, Kestrel connect with natural dye guru Kathy Hattori. As the founder of Botanical Colors, Kathy works to bring natural dyeing processes to larger scale production facilities, and also collaborates with designers on small batch dye projects.

In this chat, Kathy breaks down the big differences between conventional and natural dyes, and the scaleability of the latter. Also, Kestrel and Kathy talk about "brilliance of dyes," and how this can be interpreted differently, depending on your relationship with color and its meaning.

Nonylphenol ethoxylates (NPEs) are the chemicals that Kathy mentioned have extremely harmful effects. Research has shown that - when washed - NPEs are released from clothing and in turn, discharged into our waterways, where they turn into the even more toxic and hormone-disrupting chemical nonylphenol (NP).
