In 1926 they played Dublin in the All-Ireland Junior Football Championship Semi-Final and wore orange jerseys knitted by Poor Clare nuns from Omeath, County Louth. Another account claims that the jerseys were presented as a neighborly gesture by an Orange Lodge. [12] |
 | Carlow | Leinster | Red, Yellow Green | Up to 1910, Carlow wore the colours of the county champions. In that year a set of green jerseys with red and yellow hoops were adopted. [13] These colours inspired Derek Ryan's song "Red, Yellow And Green." [14] |
 | Cavan | Ulster | Blue and White | Royal blue has been worn since 1910; it may have been borrowed from the Cavan Slashers club. [15] The white trim was added for the 1947 All-Ireland Senior Football Championship Final in New York City. |

 | Cork | Munster | Red and White | In 1913 Cork wore blue jerseys with a large yellow "C" in front. In a 1919 raid in by British troops on the county board rooms in Cook Street, the jerseys were taken. So, Cork used the jerseys of the St Finbarr's Total Abstinence Hall team, which were dark red/maroon, and Cork have worn red ever since. [13] An apocryphal story claims that the colours derive from Church of St Anne, Shandon, which has walls of red sandstone and white limestone. [16] |

 | Dublin | Leinster | Sky Blue and Navy | In April 1913, Harry Boland chaired the Dublin County Board meeting at which "after some discussion, it was decided to adopt as the county colours a light blue jersey with a white shield bearing the city arms". [20] |

 | Kerry | Munster | Green and Gold | Adopted in the 1903 All-Ireland Football Final as the colours of the then dominant Tralee Mitchels senior team. [24] |
 | Kildare | Leinster | All White | Kildare wore the colours of the county champions originally. They played in Clane's all-white strip during the 1903 Leinster Senior Football Championship, which they won, and continued to use those colours. Clane's white jerseys were borrowed from those of Clongowes Wood College. [25] However, a separate account claims that Clane played in black and green, and that the white colour comes from a singlet worn by Joe Rafferty, a star player in 1903. [26] |
 | Kilkenny | Leinster | Black and Amber | Wore black and amber in the 1893 All-Ireland Senior Hurling Championship Final, bought from the defunct Thomas Larkins football club.

 | Offaly | Leinster | Green, White and Gold | Many teams played in the colours of the Irish flag; supposedly Offaly earned the right to use them in Leinster aftering winning a competition.

 | Roscommon | Connacht | Primrose and Blue | The Roscommon jersey was either black and amber or black and white prior to 1938. Blue with a yellow band, or black with a green hoop, was also used.

[34] [35] [36] |
