So when trying to amass large amounts of dyed blocks, It can be annoying having to try and fine the materials, especially for brown. So with the newfangled Dyeing machine (name still debatable) you can acquire a copy of the dye or dyed block, put it in the middle, just like the mass fabricator, and AYO, the advanced machine can extract the dye making the whole process incredibly efficient. So possibly 4 dyed blocks with one dye?
