It seems to me that the amount of dye required for technology is out of proportion to the rate at which dye can be produced; specifically Processions and Sewerage require a total of 39 units of Dye before you can advance through them. When you can, at best, produce 1 unit every 4 hours from a dye works this requirement seems a bit excessive to me. 4 X 39 = the quickest you can meet this requirment is 6.5 days and that asumes you are able to reset the works every 4 hours. While dye can be traded from the merchants the amount of material required for 1 dye only exacerbates the problem. I believe this area warrents a review by the developer.
