The Universal Postal Union regulations stipulated that all member nations issue postage stamps in the same colours that represented the postal rate paid on the three basic classes of mail matter. On 2nd April, 1951, postage rates were changed and colour adjustments decided upon. The Department planned to issue the 2-cent stamps in an olive-green colour and the 4-cent denomination in an orange colour for sufficient time in the future to allow for the exhaustion of these denominations in their original colours of brown and red. At this stage, plans changed to produce the 1-cent stamps to brown and the 3-cent to red to conform with the U.P.U. regulations concerning postage stamp colours. At the 13th Congress of the Universal Postal Union held in 1952 in Brussels, postal administration were no longer restricted in the choice of colours for postage stamps. The death of His Majesty King George VI, on the 6th February, 1952, cancelled the plans that had been made for the 1-cent and 3-cent denominations.
