Years ago I bought a bunch of hooks from a tier who had to stop tying. He had painted, or maybe it was nail polish, the shanks of about 1/4 of his dry fly hooks white. At the time I asked him why and he told me that the white shank kept light color dubbed bodies closer to the color of the dry dubbing material when the fly became wet. Since then I’ve occassionally done this - paint the shank white -. Now I’m not saying this actually helps or makes a difference in terms of fishing success. I’m simply asking if anyone has heard of this technique and has done it. If so, any opinion?
Sure, an old technique that I’ve read about, although never observed. As Byron says, not much point on modern flies with a thread base, but considering the more translucent nature of silk, I guess it was a more common technique is when silk predominated.
I have tried white fingernail polish on the hook for for cream zebra midge pupa s with thread and fine wire rib over the polish. it helped get closer to the right color when wet.
