Tees, educate me. | Golf Monthly

Always played with an orange tee when using a driver.Anyway a guy in the clubhouse suggested using a pink tee. Said you get a better penetrating flight because it is lower. Anyway me and a PP de idea to have a bash today using the pink tees. It did look more penetrating and I was hitting it further with a bad back. But the swing was more within myself with my back being in rag order. So that aside, what is the differance between white, pink, orange/ grey tees.
