Re: What is the best color of lure for crank baits?
The first thing I'd check would be the type of baitfish that are in the waters you fish, then match that color as best you can. Then have a dark colored bait for muddy waters and some bright color (I like chartreuse) for other occasions. Crawdaddy colors are always good, too.
As someone pointed out, the bait companies do the color thing as much to sell their baits as to catch fish. They really want you to fill your tackle box with as many of their baits as possible.
What's more important, really, than color is your fishing techniques, the action of a particular bait, and factors other than color. If you can master the techniques of fishing with different types of baits, you'll catch a lot more fish than the guy who is constantly switching colors to compensate for his lack of fishing success.
I fish a lot out of the back of my car, and carry a very small tackle box with me at all times, so I can stop by any promising water and shorefish. I have several types of baits in that tackle box, but only one of each type...to save room. I find that I may have to change types, but once I find the winning bait type, I catch the fish.
Happy fishing!
