Colour code

The birds in this project have a collar on which there are 2 characters. Both characters are vertical on the collar (turned a quarter).

The colour code consists of 3 consecutive elements:

1. an N (Neck) plus the letter of the colour
2. a hyphen (‘-’)
3. the inscription (always 2 characters)

Example NW-AB. This bird has a white collar with AB on it.
