Guild Wars 2

Hello

I accidently sold my Shadow Abyss Dye on Trading Post :

I was curious how much it costs and accidentally clicked on something and all i was looking at was confirm message that i sold it :/ the golds i recived are still on TP, can be this undo ? Can be this solved somehow ?
Also it whould be nice to see confirm message window if u want to sell something expensive, it didnt asked for anything, just click and it was gone..

Please help i lost golds for this and now i cant afford to buy another one ( the golds i have are for guild raffle )

Unlikely, that would mean having to take it back from the player that legitimately purchased your dye
