Graphene Ore 1.0.0 — Minecraft 1.21.4

Graphene helmet, chestplate, leggings, and boots are now included in
minecraft:trimmable_armor, so vanilla Smithing Table armor trims can be
applied to them using the normal vanilla trim templates/materials.

The 1.21.4 item definitions also select the appropriate vanilla trim
overlay for the inventory icon.
