Azurite from spectrum isn't obtainable

It normally spawns in the overworld and is one of the gating items for going into the deeper dark.
I recommend adding a azurite recipe to the orechid, but I have no clue what block it should use.

I like the idea of adding the spectrum ores to the orechid, but since I gated the colored leaves behind twilight forest I'm thinking I could try to make all the ores generate there.
