The colourful history of the Ulster Unionist Party is usually writ large in red, white and blue – with a strong shade of orange.
But the party is now also proudly displaying the provincial gold and red of Ulster's nine counties at its east Belfast headquarters.
While Ulster's traditional colours are more readily associated with the green side of Ireland's political divide, they are prominently displayed outside the Holywood Road offices in a crest featuring the nine-county Ulster flag in a shield, set below a crown.
The Ulster flag – more commonly seen in the All-Ireland sporting codes of GAA and rugby – features a red hand on a red cross against a gold background.
The flag more commonly associated with the unionist tradition also features a red cross, but has a crown set above the red hand and uses a white background.
Does the public display of the nine-county colours, as opposed to the six-county red and white, mean that the party has shifted its position on participation in Irish unity?
Not so, according to unionist peers Lord Laird and Lord Rogan, a party honorary secretary.
Lord Laird said the crest dated back to the original Ulster Unionist Council and had been adopted "in about 1906 or 1907".
"It's the official badge of the party and dates back to the first Ulster Unionist Council, which was obviously before partition," he said.
Lord Rogan said the emblem was engraved on the UUP's official plaque and was embossed on the party's "better quality letterheads".
Alastair Patterson, the party's chief executive, said the crest on its Cunningham House headquarters was "an exact copy" of the council emblem.
"Cunningham House is on a prominent site on the corner of the Holywood Road and the Parkway dual carriageway and when we moved here last year we wanted a symbol that would make the building stand out," he said.
"So we made an exact copy of the original crest."
Although the gold and red Ulster flag has always been the UUP's official emblem, these days David Trimble is more likely to be seen standing in front of a map of Northern Ireland with a Union flag superimposed on it.
The Ulster Unionist Council was formally constituted in March 1905, the year in which Sinn Féin formed.
As well as the Ulster flag, the party's crest included a royal crown – a feature later included in the red and white Northern Ireland flag.
Under Sir Edward Carson, who led the party between 1910 and 1921, the Ulster Unionist Council organised constituency associations throughout Ulster, including Donegal, Cavan and Monaghan.
But after partition those counties found themselves in the south and ceased to have any representation on the Ulster Unionist Council.
The Ulster flag is based on the red hand emblem of the O'Neill chieftains of Tyrone – renowned for their strong resistance to English rule.
The red cross on a gold background comes from the flag of the de Burghs, the earls of Ulster until 1333.
