If there is no light, how can color be perceived ?
Match the hatch by day, and use them at night.
During the day pay attention to how the lure works, it has to mimic what the fish are on, don't just cast and retrieve. Then apply that technique at night.
Practice and confidence will equal success.
Or you can take the art out of it and just throw eels.
Eels are easy and they work.
