A colleague of mine has just sent out an e-mail in a green font which prompted me to recall that, in my early life as an MoD civil servant, my Assistant Secretary used green ink. This was part of an old established principle that different grades used different coloured inks. Myself, as a lowly Exec. Officer, could only use blue! Sounds a bit Victorian but not a bad system in a paper based office. Can anyone remember all the colours and grades; did it apply in the Army?
