Morpho butterflies remain a vibrant blue throughout their lives, without ever needing a coat of paint to spruce up a dull finish. The scales on their wings are made of many layers of proteins that refract light in different ways, and the color we see often is due entirely to the play of light and structure rather than the presence of pigments. Teijin Fibers Limited of Japan produces Morphotex® fibers. No dyes or pigments are used. Rather, color is created based on the varying thickness and structure of the fibers. Energy consumption and industrial waste are reduced because no dye process must be used. In 2011, Teijin Fibers Limited stopped manufacturing Morphotex.
