Green moon: Makes cacti, sugar cane grow taller and makes trees spawn taller, passive mobs spawn more and hostile mobs spawn less, and get better loot from chests, villagers trades are sort of cheaper and get more from their trades.
Yellow Moon: Spawns lightning rarely often and randomly and has 25% chance of hitting the player, storms are worse during the yellow moon and mobs transformed by lightning are stronger (witches regenerate, super charged creeper, and pigmen are hostile)
Purple moon: Enchanting during purple moon increases the max enchantment level up by +1, and potion effects are extended. Also mobs with weapons, have a higher chance of spawning with enchanted weapons, and stronger potion arrows, has a 25% chance of a cave spider to spawn instead of a spider
Green, unneeded. We have the Harvest Moon.
Yellow is pretty much a mix of the Blood Moon and isn't needed.
Purple, unneeded. If you want higher enchants, use Apotheosis.
It adds a way of doing this.
