The eyes of bass are monocular, not binocular which means that unless the bass is focusing on the line and bait with both its eyes, it can’t see the braided line. However, if both eyes are focused in the same direction, it can detect it more easily.
Marine biologists have found that bass can see colors as well as the shades of grey, black, and white. However, their detection of colored objects might be compromised in conditions with low light.
The clarity of the water itself impacts the visibility of the braided line. If you use a clear line in clean waters then the chances of it being detected are slim. But a bright-colored line in the same conditions will automatically be detected.
Try to match the color of the water that you'll be fishing in. Clear blue water would call for white or blue, while murky water would work best with clear or green braided lines.
Primarily, red and yellow lines are to be avoided. These are clearly visible whether you’re angling in clear water or the murkiest water due to the bass’ ability to see red, green, and combinations/shades of the two.
