For the most part, color should be the very last consideration on your list of factors for choosing line. It simply does not matter that much. In fact, I’d look around for colors that could potentially get you a better price on a line. Sometimes, certain colors get discontinued or aren’t as popular, and can be purchased for less money. However, if I had to choose a color for copoly, fluoro, or mono, I would simply want clear. It’s the most popular option and your best bet. As far as braid colors, I wouldn’t worry about it too much either. The line is already visible under the water, and whether you get blue, neon yellow, white, or red won’t matter too much. Personally, I like to try and get a white line, as I think it might blend in better with a bright sky, while not standing out too much underwater.
