What We Do

Botanical Colors offers natural dyes and education to textile and fiber arts artisans around the world. We support regional farmers, organic farming, regenerative soil and are forever excited creating new plant-based colors out of our Seattle-based studio.

Seattle-based Botanical Colors was founded in 2010 by Kathy Hattori. Botanical Colors supplies natural dyes to artisans, dye houses and industrial clients seeking the beauty and environmental and social benefits a natural color palette offers. In addition, we offer classes and educational materials to teach natural dyeing to a broad audience.

We also offer consulting packages for production dyeing, as well as marketing and navigating the landscape of the natural dye and fashion industry. Inquire about our consulting services here. 

Along with our wide assortment of organic, GOTS certified and food waste dyes sourced from all over the world, we also continue to support a network of regenerative farmers here in the United States.

I founded Botanical Colors in 2010 because I wanted to change the textile industry by offering a safe alternative to petrochemical based synthetic colors. My solution was natural dyes: colors that were beautiful, regenerative and non-toxic. My journey took me around the world helping dye houses, brands and non-profits create colors from local sources or time honored traditional colors. Along the way, we built an amazing community of makers, scientists, artists, historians and activists eager to share their work and support, and I am grateful for their commitment and support.

  1. Is it possible to dye cotton or abaca paper with cochineal insects? I teach a paper making class and would like to use cochineal dye instead of pigments. We would be adding wet paper pulp to the mordant bath and dye bath. Thank you, Wendy

  2. Dear Kathy and Amy,
    What a powerful and elegant organization you have built to change the world for the better in so many ways. Thank you for your inspiring actions to create beautiful color for the world, provide amazing opportunities, and promote such ecological and sustainable practices. I’ve always wanted to take your workshops, but I’m at home with two young children so I’ve had my hands full. Feedback Friday’s have been SO great for me, I watched each episode with gusto and inspiration- thank you for this gift that has really fed my spirit. I look forward to taking Aboubakar’s mud cloth workshop soon and truly can’t wait, what an amazing opportunity! I look forward to learning so much more from both of you and your team.
