anyone that knows me knows I fish a crank year round, and have for 30+ years I always have 2 -4 tied on I always always always have a square bill of some size on and a deeper rounded bill a jerk bait (yes year round) and a lip-less (yes year round also)always in some shad pattern. the only time I personally worry about color is when the water is stained or at night , then i will go to a darker color. I use mostly 4 basic colors white, gray, red, chartreuse. the more clear the water and bright the skies the "less" color i use. hopefully this helps you get started. also for the record ( I have been throwing the same color and size square bill since Sept and weighing in limits each time). I had an old friend tell me one time that most lures are designed to catch fishermen not fish.
