Dye Weapons?

Would be really cool to Dye weapons, tbh I really Love the Odin appearance and the only sad thing I have is that the Great Shin-Zantetsuken is Silver in this case so my Dark Knight cant have a matching dark sword. On a side thing would be cool to have a dark variant of the Zantetsuken for Samurai and Dark Knights.

Some weapons are dyeable, but there's no real logic to whether they implement it or not, besides that it's more likely for endgame weapons.

I wanna dye ilvl 180 PVP weapons. The gear can be dyed but these weapons cannot? SE pls.
