When considering how the visible color spectrum (the red, orange, yellow, green, blue and violet of a rainbow for example) reacts as it enters the water, spectrometry confirms that it is the color red that is first to be filtered. It is this natural filtering, combined with the material composition of Cajun Red Line, that allows a more realistic lure presentation, and leads to more hook-ups.
Even above the water, Cajun Red Line has the advantage over clear lines. Because natural scenes rarely contain fully saturated colors, Cajun Red is much more visible above the water, allowing the angler to better see the subtle twitches in the line caused by an active lure or fish strike.
