My relatives are convinced that only "golden" (brass) hooks work well for them for ice fishing. They say when they use dark or white steel hooks (either above the jig or just two loose hooks with weight on the end of the leader) they catch significantly less than with the same setup but with brass hooks. I think that hook colors affect bite in some way, but the difference is often minuscule. Have you ever noticed any difference?
I think that these people have good points. Through the ice and in summer time pan fishing I like to use gold hooks. If my bate don't cover my hook I think it gives a little flash. And on my crawler harness I use red because the hooks seem to be better hooks. One thing for sure is that most fishing lures and hooks are more man catching then anything. If you fish long enough with one thing you will catch fish, That's way try and stay natural as you can. Good luck
