The King’s Colour for the Royal Regiment was the British Union flag with the Circle of St Andrew in the centre and crown above. The regimental number was in Roman Numerals, in this case I in the upper canton, but obscured by the wavy pile or ray of gold which signified that this was the Colour of the 2nd Battalion. The Royal Warrant of 1751 explains the wavy yellow flame coming from the upper corner: ‘The Distinction of the Colours of the Second Battalion, is a flaming Ray of Gold descending from the upper Corner of each Colour towards the Center.’ This distinction was retained until 1832.
The dimensions of the King’s Colour at this time was the same as the Regimental Colour: 6 ft 6 ins wide by 6 ft 2 ins deep. The length of the pole or pike was 9ft 10ins. The spearhead at the top was 4ins. The tasselled cords were 3 ft long.
