The Regimental Colour is a dark blue flag with a small Union Flag at the pike head. The Colour carries similar central embellishments as the Queen's Colour, with the exception that the cypher of George IV replaces that of the reigning monarch and the unit numeral is below. The Royal Cypher is at the other corners. The cords and tassels of both the Queen's and Regimental Colour are gold interwoven with silks of the Commando lanyard.
