Solution: colored labels. Or those colored round sticky dots that can go on the cap.
Sire, the coloured dots you speak of are $6.90 for a small box where I am in Australia. True, many different colours, but it is defeatist from a cost/economic viewpoint. I am using a piece of masking tape upon which I scribble what is in what tube.
