Mueller "M-Tape" comes in a variety of colors. This is what I use. You can actually get it at most Sporting Goods stores. d***s has some wierd no-name brand. Check your local "smaller" Sporting Goods shop. If you have a Sport Shoe Center store, they have it.
Here's the Mueller website showing all the colors:

I have a variety of colors to personalize my own and my team's poles. It's pretty cool stuff.
