The color code consists of 3 consecutive elements:
- the letter of the colour
- a hyphen ("-")
- the inscription (always 4 characters)
Example W-ABCD. This bird has a white colour ring with the inscription ABCD on it.
In some projects there may be a special sign (eg a dot) on the ring that may be important in recognizing the bird. Example W-A.ABCD
