Although the official design of the flag at the College of Arms does not specify colours beyond [[Azure (heraldry)|azure]], [[argent]] and [[gules]] (blue, white and red, respectively), according to [[Graham Bartram]] (chief vexillologist of [[Flag Institute]]) the colours blue, red, and white are:<ref name=Flagsofworld /><ref name="auto"/><ref>{{Cite book |last=Bartram |first=Graham |title=British flags & emblems |date=2004 |publisher=Tuckwell Press |isbn=978-1-86232-297-4 |location=East Linton}}</ref>

All [[Web colors|HEX]], [[CMYK color model|CMYK]] and [[RGB color model|RGB]] specifications for the [[Pantone]] colours are taken from the official Pantone website on the webpages of the corresponding colours. Although these colour specifications are official, not all of the colours are completely congruent. This is due to different specifications for different types of media (for example, screen and print).
