Taken from the Wiki: https://runescape.wiki/w/Dyes#Treasure_Trails
These dyes may be acquired from hard, elite, and master Treasure Trails and can be used to dye most level 90 and greater armour and weapons. This process is irreversible, the dye is used up in the process, and
the dyed versions of equipment become permanently untradeable unless killed for it in dangerous PvP combat
. Even then,
dyed weapons lost on death are simply converted into a broken version of the original
, with the dye being lost in the process.
