HC Deb 10 March 1948 vol 448 c148W
77. Mr. Gammans

asked the Postmaster-General if it is with his knowledge and approval that the district postmaster of the Western District Post Office, Wimpole Street, W.I, in a letter of 16th February, 1948, requested the Road Haulage Association to discontinue the use of pink cards for postal purposes on the grounds that pink is a bad colour for sorters.

Mr. Wilfred Paling

I am aware that the Road Haulage Association has been asked, and has agreed, not to use a particular shade of pink paper for postal purposes. The Post Office has always discouraged the use, for ordinary purposes, of postcards and envelopes which are made up in bright and vivid colours as they tend to be tiring to the eyes and to slow up the process of sorting, particularly when handled in large numbers and in artificial light.
