Guild Wars 2

While leveling scribing, I saw that there may have an error in the pigment used in the crafting recipe of the various ink set.

Grandmaster : white & black pigment
Master : purple & yellow pigment
Journeyman : blue & orange pigment
Fine : yellow pigment
Basic : red pigment
Simple : brown pigment

There is 9 pigments in the game: white, black, purple, yellow, blue, red, brown & green.
Yellow is used twice while green is unused. Anything else is used at least once.

Isn’t that an error ?

It’s reported in wiki as an “anomaly.” Another way to say that it’s probably a mistake. Most likely it’s been reported but you can always make a thread in the Bug Forum, just to be sure.
