I found a red dye in a treasure box yesterday in the beta. I then tried many combinations and could not figure out a recipe.

Does anyone know if it is a drop only or can they be crafter as well?

I found dye last week or so, white one and I just simply used it on my mages robes.
Dont know if there are any other uses for them cause I only had one
