Specification for Coding Colour Marks
The BTO’s Ringing Software Technical Panel have accepted a coding scheme for recording colour rings/flags/tags/colours with and without engraved digits etc. Many colour ringers and colour ring co-ordinators have kindly provided their knowledge and assistance in the development and review process of this standard. It is hoped that the standard can be adopted across Europe in order to assist in the exchange of unambiguous information.
