In 1962 SDC became a registered educational charity, and in 1963 SDC was granted a Royal Charter and became the only organisation in the world that can award the Chartered Colourist Status in recognition of individual professionalism. The Royal Charter in its original form includes a Schedule detailing the By-Laws the Society operates under. These By-Laws have been revised over the years and at the top right of this page is a link to the current By-Laws in force, which should be the ones referred to and not the original Royal Charter Schedule. Amendments to the Royal Charter and By-Laws must be undertaken via and agreed by the Privy Council. The Rules however are set by the Board of Trustees and agreed at the AGM. A copy of the most recent Rules currently in force is available via the link at the top right of this page. We operate globally, and run an international programme of events and activities.
