Locked Dye Color Applied to Armor
Certain armor sets have automatic pre-set dyes when you equip them. Pyre is one of the pre-set dyes for the set of armor you’re wearing.
I had changed the pre-set dye colors to something else for a few days then changed it to pyre. Even if it is a pre-set dye color for the armor it shouldn’t allow you to reapply the locked color back to the armor set after you have changed it.
If you apply a dye color you do not have to an armor, it will often default to it’s pre-set dye. In this case, it happens to be Pyre, which you have yet to unlock.
