Maybe it's Night Wizard? From what I understand, it's pretty similar to 11eyes, at least in concept.

Sounds a bit like Persona 3, so maybe the Persona 3 anime? The moon turns green during the dark hour, so maybe you just misremembered the color?

You might try looking on Bad Moon Rising if you haven't already.
I'm trying to find an anime about a group of (I think)students that have to fight off monsters whenever a red moon appear. I don't remember much of it, but there is one part in an episode that stands out. The students are relaxing someplace when the moon appears. Some of the students go into some tomb like place where there is a door and two torches. I believe there were some murals or hieroglyphs saying that to get the door open they have to change the color of the flames from red to (I think)blue and green. They do this by putting something in both of the torches. I asked this question before and got the 11eyes anime for an answer. I watched it, and it was not this anime.
