I was asked the other day, if there are any laid down standards when it comes to colouring in schematic or block diagrams that are used in training. I have never come across anything myself in either the military or civilian sector but I wondered if anyone else had? I normally use red, blue/black and green for electrical cables but have never really considered any others.
If you have any useful info on this one then please post it here as I am sure it will be useful to everyone.
PS. I've also raised this discussion in content development to see if anyone in that group has ideas/
