So, maybe before we spend all this time thinking of new ways to trick a fish, maybe we should think about it from the trout's perspective? Exactly what does a trout see under water? Well, to know that you have to have an idea of how the trout's eyes work.
I've heard many of the theories about fly color before : red shows an injury, making for easy prey; black shows up best in most conditions; flash helps draw the fish's attention; use a yellow colored fly when the water is tea-colored; etc. If any of this is true, why is it? Well, I went looking for an answer.
Not being a scientist I was quickly in over my head with complex & detailed explanations I didn't understand. After all, I just want to to know how to catch more fish. I found the most down-to-earth explanation on a blog called Gink & Gasoline. It gave me the info I was looking for from an angler's perspective.

So before you start to invent a new fly pattern, or while choosing which one to take out of your fly box before you start your day's fishing, think about how what you're doing is going to look from the trout's point of view. Thinking like this can only help you to catch more fish.
