The darkening is what originally made me think double enchi. I am learning the hard way that in order to really emphasize enchi I need to add pastel. The odd thing is that a lot of people suggested fire complex to lighten up my enchis, but this seems to go the other way. Not that there is anything wrong with dark snakes if that is what you are chasing. I'm having my best luck with phantom/pastel/enchi combos for the coloration I like right now. I'm going to add fire this coming season. Hopefully I do not get darker.
