Re: Why so many spinner colors?
In my opinion, you already answered your question, to sell more flies. I tie four colors, rusty, cream, black (for tricos) and grey. Rust and black have done the best for me as most spinner falls occur at dusk or dark the dark silhouette is easier for the trout to see and rust covers just about everyother situation.
