Well of course a company that sells UV lures is going to tell you how much bass love UV, that's the gimic they are trying to push.
You guys missed what I was trying to convey about color. I'm not saying color doesn't matter, I was trying to say just because a color is successful doesn't mean the bass can see that specific color. Perhaps they actively didn't like the colors you were previously using, or perhaps they liked the grey that the blue lure looked like.
Things with low success rates like fishing breed anecdotal based superstitions, its just human nature. I have no doubt that you guys have had great success with blue lures, I have myself as well. That doesn't negate that bass have limited blue vision.
