There seems to be an issue with the animated armor, where the dye color is being accessed while it isn't initialized yet.
It happens with all the animated armor pieces and some dyes, seen logs from all kinds of dye items:

dye_arcanist_boots
dye_battlemage_leggings
dye_archmage_spell_book
dye_sorcerer_boots
...

Versions:
ars_nouveau-1.20.1-4.2.4-all.jar
Forge - 47.1.44
Minecraft 1.20.1
