Between 1919 and 1952 "friendly" matches took place annually between the clubs on a home and away basis. There were also memorable encounters between UCD and TCD in the Leinster Senior Cup when the draw brought the sides together. Following the Senior Cup win of UCD over DUFC in 1948 by a dropped goal to nil, the idea of a Colours match was discussed between Harry Thrift of Trinity and Sarsfield Hogan of UCD, who had served together on the International Rugby Board, on which basis each University club would award Colours for the season. Lengthy negotiations ensued and with the cooperation of the IRFU committee and of the Lansdowne and Wanderers RFCs a scheme for an annual Colours match was finally agreed. The two Universities would play once a year in December. Each University would act as the host in turn and be responsible for the management of the match and for the entertainment. The host University, after consultation with the other side, would invite the referee for the match. A formal teams' dinner would be held after the match. It was envisaged that the match would be played on a Saturday. Increasing numbers of representative matches and the limited number of Saturdays on which Lansdowne Road was available led to pressure to change the match from Saturdays to a mid-week date.
History
The Colours Match was inaugurated on 13 December 1952 at Lansdowne Road with the first title taken by UCD Trinity gained their first win in 1954 and the first drawn match came in 1955.
