I was messing around with the forge lexicon on the mindcrack mod pack in the FTB launcher and found out that you can exchange inc sacs for liquid black dye in the forge lexicon. buckets and when you use a liquid dye bucket on a piece of wool you get the colored wool and the bucket back. this could be a problem when EE3 comes out but i think the only way to change this would be to not let the forge lexicon exchange dyes for liquid dyes.
