Help with Item Modifiers

I am attempting to modify the custom_model_data of my item with a command. My item json: { "model": { "type": "minecraft:model", "model": "custom:item/hat", "tints": [ { "type": "minecraft:dye", "default": -1902854 }, { "type": "minecraft:custom_model_data", "index": 0, "default": 16711718 } ] } } My item modifier (generated with misode): my_dp/data/custom/item_modifiers/hat_change.json { "function": "minecraft:modify_contents", "component": "minecraft:container", "modifier": { "function": "minecraft:set_custom_model_data", "colors": { "values": [ 5897984 ], "mode": "replace_section", "offset": 0 }, "conditions": [] }, "conditions": [] } The command I'm using: /item modify entity @s weapon.mainhand custom:hat_change The result is in the attached image. The item itself is working as expected, but I can't get the item modifier to work. Not sure what I'm doing wrong. I'm pretty sure everything is in the right place. edit: I'm trying to change the custom_model_data color btw.
