Color
Many anglers draw fine distinctions between colors of leaders although some prefer it just as it comes from the tackle store. There are a great many ways to dye gut, the simplest, and I believe the best, being those given many years ago by Salter: "To stain hair or gut a pale sorrel color let it remain a few
minutes in a cup of strong coffee or black tea. To give it a pale slate color, mix water and black ink in equal parts and put the hair or gut in it for a moment only. For a grayish water color (mist) dissolve a little alum and indigo in boiling water, let it stand until it is cold and dip the hair or gut in it until it has acquired the tint you wish."
