How To Create Plant Pigments

In this project I researched and learned through trial and error different ways to make plant pigment and found the most beginner friendly way to homemake pigment; Laking. Laking is a chemical process using an alkaline and an acid to extract pigment from plant dye through an exothermic reaction. I then used the Laking method I found to create my own pigments to turn into water color and to teach others how to create their own pigments. I focused on using University of Delawares Fresh To You Farm’s vegetables and herbs to create my pigments as my Envision internship is focused there, and I wanted to be sustainable in the resources I was using. Pigments have been made from plants by humans for a long time, dating as far back as 100,000 years ago, though their processes were far different than those used now, as modern day chemicals and equipment has made pigment making far faster and easier. Although the physical processes may be different, the intent is the same; create something new. Through this project it is my hope to keep art alive through nature by simplifying the process of pigment making and teaching others how to do it themselves.
