1. Clear Water. Color selection is critical when faced with clear conditions as fish are able to give baits a serious once-over from a distance. In clear water—match the hatch. I hate using that all-so-tired cliché, but it's so applicable. Clear water dictates a pattern that closely mimics the predominant baitfish in the particular bay, bayou, river, flat or blue water you're fishing. If it's killifish, then by all means use a killifish pattern. Knowledge of the local water always helps with clear-water color selections.
