Indigo is a natural dye derived from the indigo plant. It is one of the oldest dyes, yet is still in use today. Throughout the centuries, indigo has been a popular and sought after commodity. Various cultures revered the color for many reasons. It was used in Japanese art, in the blue military uniforms, and is the iconic color for blue jeans.
The process of dyeing with indigo is an adventure- almost like a chemistry experiment- you never know exactly what the result will be. The dye is not soluble in water until the oxygen is reduced and a yellow green liquid is produced. When the yarn is immersed, then removed, the indigo oxidizes and a transformation from yellow-green to a gorgeous blue evolves. This is why indigo has been known as “Blue Magic”.
