As we've seen, down the years Donegal occasionally wore variations of the Ulster jersey and in 2007 on his first championship start away to Leitrim, a 17-year-old Michael Murphy wore the jersey, on a night when he scored his first championship goal. Donegal sneaked through to win 1-16 to 1-14 after extra-time.

Usually against Antrim, Donegal have come up with something a little different, like this one in the Ulster opener in 2009. An almost all green kit looked the part, but Donegal didn't as they were shocked by Liam Bradley's team in Ballybofey.

Anoraks might recall the green number in 2009, as similar to one worn back in 1984, and again in 1985, when Donegal were crowned All-Ireland Vocational Schools' champions. A collector's item if ever there was one.

Back to the future again and perhaps the standout fixture for Donegal's white jersey - frequently worn - was the 2012 All-Ireland SFC against Kerry, which was the first ever championship meeting between the sides. With Jim McGuinness at the helm, Donegal were 1-12 to 1-10 victors.
