 The original design of the cathedral also called for more extensive use of marble, particularly to the floors of the nave and sanctuary.The architect's original intention for the leadlight windows was to eventually house stained glass when funds permitted, but in the interim to use gold and light blue glass as per his design for the Sisters of Mercy St Bernard's College, Herberton.However, Bishop Cahill did not like the colour blue and requested that the windows be constructed with a field of burgundy red glass with an amber border.
