The reason red fishing line is so effective is simple—visibility. How Light Penetrates Water To understand the science behind red fishing line, we first must discuss how light penetrates water and the impact of light on successful fishing. The color of the lure has long been a concern of anglers. Correct lure color is very important to your success. Bait with a color that produces well on topwater may not be effective in a deeper presentation. This difference in performance is mainly due to how color relates to the amount of light in the water. Lures are available in all colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet. Experienced anglers often run lure colors of red, orange, or yellow when a lure is presented in the portion of the water column with the most light or topwater. The colors on the other end of the rainbow, which includes blue, indigo, and violet, are used in darker or low light situations. The reason for this is the spectrum of light changes as it penetrates the water. Line color, on the other hand, can add to the success of any presentation. The first color that disappears as light penetrates water is red which explains why red fishing line is so effective. Red disappears at 15 to 30 feet of water. A line that is invisible to fish will not spook your target and will make lures look more natural. For this reason, red will put you on more action in deeper presentations. What if most of you are fishing in less than 30 feet of water? Red line should also be your first choice. This secret is now being used by pro bass fishermen to catch more fish in shallow water. The key here is your ability to see subtle movement in the line to detect the bite. Clear line is very hard to see and can lead to missing the nibblers. A bass can inhale the bait and spit it out before you can detect the line movement. Rigging Red Line Rigging is important to red line in shallow or deep water. Running red line directly to your favorite lure may not be the way to go. Tournament anglers often use a 4-foot clear fluorocarbon leader on the end of the red line. This approach should be applied anytime red line is used. Ice fisherman use 4-pound test red line with fluorocarbon leader to detect the bite of small panfish. Salmon anglers trolling with multiple lines will find red line is easier to see and more manageable with fewer tangles. Red Is The Answer When it comes to the color of your fishing line, the answer is red both above and below the water. Follow this tip for more action and less downtime. Live bait, plastics, cranks, and spoons all become more effective on red line.
