patch 1.19 brought major revisions to item recipes in Final Fantasy XIV, it also brought about a big shift in dyeing items. While it was easier to color items with several universal dyes, it was also near-mandatory to have certain colors of equipment, as dyed variants provided additional statistical benefits for characters. Players were a little miffed about this, even if the stat changes weren't that huge -- which is why patch 1.20 will be taking the change a step further and uncoupling stats from color.
Under the new system, there will be ways to create specific variants of equipment with improved stats, but color will no longer be linked to the final stats for the item. Items currently possessing multiple color variants will still have multiple variants, but the main differentiation won't be whether they're brown or black. It's not an earth-shattering change, but it's certainly one that will make Final Fantasy XIV fashion police much happier.
