From their rebranding blurb:
The history of Gwent has also played a big part in our new brand. It is represented by the introduction of three amber fleurs-de-lis – symbolic across many crests in our region.
The club will adopt three main colours going forward. Black and Amber to represent our city and history plus the Blue of Monmouthshire and Gwent to represent the region we play for.
All three colours will feature on new home and away jerseys, while our new away shirt also encompasses the colours of all the clubs without our region.
The Dragons' tail - that has adorned our badge since 2003 – will remain on the collar of our playing jerseys.
