I came back to GW2 a week ago and had the toxic set pieces equipped with a very boring white dye... I have tried to do the best I can to make this pieces look good and this is the best result so far.
It's very difficult to replicate the glow of the toxic set. The main color I used on the toxic set pieces also didn't look the same on most chest and leg armors I tried to make this work with. Astonishingly it works with the council guard armor, but I still had to find a solution for the bounty hunter chest... Sometimes, in the right light (or in this case the bad light) it gets very apparent that it's not the same color.
