I put a BRIGHT color in the first section of my leaders. Example, on an Olive leader, I add Chartreuse. It is the first 18" or what ever the first section is on the different length leaders. My most popular leaders I call Desert Camo, the other is Forest Camo which are shades of Browns or Olives with bright first sections. And of course with the off set pegs, the colors do blend nicely.
The contrast is a great indicator. I am a wet fly freak and this works killer for me.
