I want to make an item use a single greyed out texture to be any colour, much like leather armour.
I would do this with OptiFine but I don't know if it supports that or how I would even do that.
All I know is that I want to use the item's NBT data from this path
Item.tag.armElyData.chestplate.tag.display.color
to do it. The value is modified by a datapack and stored as a decimal.
Let me know if you need any more information from me.
