To understand the benefit of Phantom Red, one must understand the behavior of light as it penetrates the water, because line colors do not look the same underwater as they do in air. As line descends below the surface, water absorbs the wavelengths of light selectively, one by one, as depth increases. Red is the first color to disappear, at a depth of 15 feet (which is why underwater photographers often use red filters to restore red colors in their pictures).
