With 19th April update comes scribing cost rebalance.
One of most significant part of scribing price being brown pigment that used in nearly all recipes. Because of that it much more expensive than rest of pigments. (~25-28s vs 5ish for the rest)
After update it use probably will be reduced to a more reasonable amounts that will make scribing costs much more affordable. Or other pigments will be used for basic recipes as well instead of brown only)
That pigment mostly comes from brown specter dye salvaging (uncommon dyes 2-4, masterwork 5-8,rare 9-12 pigments per salvage)
So i think prices for these brown dyes and pigment itself will crash a lot and finally be at level with a rest of dyes and pigments.
