I know some people wont use the same tee on any hole... They only hit from a tee once then discard it.
Last time I played my local course I was following a ladies competition, and at every hole there was a red and pink tee left behind.
For me the closest I come to one is trying to have everything in my bag bright (fluro) orange. Orange tees, balls, bag, glove etc... I still have a few things to go before I am completely orange, but the remainder of my equipment is fluro green, bar my clubs which I will detail with orange paint ASAP.
