Nighttime Navigation Questions

[DBreskin]

I was also at the Wolfeboro fireworks, anchored just off Brewster beach (with only my anchor light on). I was distressed seeing a couple of pontoon boats with LED lights under their decks, illuminating the full length of their metallic pontoons. Two of them had color-cycling lights, changing from red to blue to purple to green. It was disturbing to see both red and green on the same side of the boat.
