I’m looking for yellow dye. Not yellow-like, but simple yellow (#FFFF00). Is it possible to create so many dyes and omit yellow one? Yes
ANet, plz, add to the game few yellow dyes
No yellow dye, why?
I remember reading a blog about this some months back. Apparently the true yellow colors are a very narrow spectrum range. If you go one way or another, to one side there is the greens and on the other there is the reds. This means that only a few colors can be true yellows. Others have a greenish to reddish tint to them.
Looking at this chart shows you how narrow the range is.

Unfortunately it’s a fact of physics. Not much the Devs can do about it.
You can use that chart to select a dye with the closest color you want.
