The Colour Index is published by the Society of Dyers and Colourists (SDC) and American Association of Textile Chemists and Colourists (AATCC). First published in 1924 it is the definitive guide for essential colorants.
The Colour Index is organised and run by two technical boards, one responsible for the Dyes, the other responsible for Pigments & Solvent Dyes. These are committees of professional people from the industry they serve.
