Is there a way to get the items dropped as part of a treasure pool to be one of the dyed variants instead of the default color?
yup! instead of using this Code: { "weight" : 1.0, "item" : "itemid" } you use this Code: {"weight" : 1.0, "item" : { "name" : "itemid", "parameters" : { "colorIndex" : colorOptionIndex } } } the color option index is the index of the color option in your item file. it starts at 1
