Yes. A lot of fishermen argue on this point and whether or not it is true. One argument is a white lure seems unfinished, like it was forgotten to be painted. With this unfinished quality, some fishermen think that fish won’t be attracted to it. Think about deepwater fish and their traits for a moment though.
Deepwater fish, like some muskies, can not see color well or can only see in reds and greens so they rely on a flash of light or action in order to see prey. A dark lure will not reflect a lot of light, so it eliminates the possibility of a musky seeing the action of the lure. Without that action and light, you won’t catch the attention of the musky, so you won’t catch as many fish.
Also, muskies primarily eat baitfish or other forage fish in lakes and rivers. From the lateral line down, these fish are silver, white or a washed out green. Seeing a white lure makes a musky think the lure is in fact a baitfish, so it will bite.
Yes black lures are effective, but using a white lure from time to time can give you the advantage when fishing for deep-water fish. I’m not saying to retire your black or darkly colored lures, but use a white one as another option, another tool to help catch the prize gamefish you really want. It could mean the difference between coming home with guppies and coming home with a trophy.
