The schedule of moonlight triggers spawning in most corals. the color is unimportant, what matters is the timing. Lunar cycles are out of phase with day/night cycles; so the "moonlights" hobbyists use that come on right after "sunset" are not at all appropriate for simulating moonlight. Also, all the lights hobbyists use are *way* too bright if you're looking to actually simulate moonlight. Full moon at 30' deep is nearly pitch black.

All that said, yes, you can trigger reproduction in an aquarium by properly simulating lunar cycles. Its been observed by many for planulating brooders like Pocillopora damicornis and more recently even for Acropora.

But its very unlikely to happen in a home hobbyist tank for a variety of reasons.
