I guess I'm confused as to what you expected to happen when you mixed your two dyes. You say that you combined two different QL dyes that shared the same RGB. If you were to dye two items, one with each of the different QL dyes, would they not be different colors? Almost every other item in the game, when the QL of the same items are different and combined, the result is the new combined average of the item, based off of the QL and the amount combined. For example, if I have 50ql iron and combine it with 50ql iron, I should expect to have 50ql iron afterwards, and I do. But if I combine 50ql iron with 25ql iron, the result is shifted to a lower ql, again based on the amount of each QL combined. Why should dye be any different. It is how the game has worked forever. Even now if I mix low QL red dye with high QL red dye, one would never expect to retain the high QL dye. If that were the case it would be much to easy to keep making high QL dye, just keep adding low QL garbage dye to keep up your stocks of high QL dye.
