| Abstract | ||
| The only colourful pigments that were available to humanity were (and so) natural dyes until the first synthetic dyes were found in 1856. Indoor and outdoor renewable and biodegradable dyes are sustainable. However, they cannot satisfy the vast demands of the textile sector because of the dominant use of land for food and feed. The over exploitation of natural resources might cause deforestation and imperil native species. Safe synthetic colours may not be used under the Global Organic Textile Standard (GOTS), while natural dyes may not be used for endangered species. There have been a number of global initiatives to overcome inherent colour defects. | ||
