However, I still have a good handful of the colour recipes that I can do fairly easily. I haven't gone through the black/grey ones yet.
I'll need to do some research on where I can get the ingredients I need, but for the time being, here's my shopping list:
Ripe buckthorn berries
Litharge of gold
Some of these will make duplicate recipes. So, for example, the ingredients listed would make two or three different blue recipes so I can compare and see which one I like best for specific purposes.
