+		These are recolored "Dyeworks" variants of items. Dyeworks is a game of
+		chance: if you have the "base" item and a Dyeworks Hue Brew Potion, you can
+		[combine them][dyeworks] to receive a random color variant. You keep both
+		the new item *and* the base item.
+
+		If you don't get the color you want, you can use another potion to try
+		again. It's also common for users to exchange the variants they don't want
+		via "NC Trading". (Potions can be bought individually, or in bundles of 5
+		or 10.)
