If the fish can see the light they'll be spookier, plus like what was posted above, letting your eyes adjust to the light.

Black so it's a contrast against any light that is coming down from the moon or the stars. I've also had good luck tossing spinnerbaits at night even if they didn't stay on the surface. Noise so their lateral line can help them home in on it.
