There is no need to narrow it down to brand, batch no. etc... a simple blue, green or purple will suffice!
I worked with a guy for many years who refused to use blue ink- ballpoints, rollerballs, pens... just not blue.
I also had another colleague who wrote all of his trade tickets in green (you can imagine how many years back that might have been).
My favourite - Green
