i think we all know they come in 100 different colors so we will all go buy 100 different colors, but matching the natural bait is important on bright days.... with jigs, i think you only need 2 or 3 colors, with crank baits maybe 4 or 5..... i have been out many days where fish would bite on model a bombers, no matter what the color, and i have been out on days where white crank baits work, doesn't matter what brand

keep in mind that depth and speed are directly related to color
