Changing colors of custom potions based on effects

[OberonPuck]

I made a custom potion item that extends PotionItem and it works perfectly. I provided it with a multi-layer model with two layers, one for the "glass bottle" and one for the "potion liquid". However, when I loaded in, all of the custom potions used the same, default texture. So I went into ItemColors and tried to replicate the code that registers the colors of other potion variants using PotionUtils.getColor. Even though the game didn't crash, the colors of the potions didn't change.

I've checked multiple threads on this forum about similar issues, but they are either outdated and some of the methods don't work or they are only tangentially related.

TLDR: How do I change the color of my custom potions' texture to match the effect?

Here is my code for my potion item:

//Commented out imports

public class GelledPotionItem extends PotionItem
{
	public GelledPotionItem(Item.Properties builder)
	{
		super(builder);
	}
	public ItemStack onItemUseFinish(ItemStack stack, World worldIn, LivingEntity entityLiving) 
	{
		return null;
	}
	public int getUseDuration(ItemStack stack)
	{
		return 0;
	}
	public UseAction getUseAction(ItemStack stack) 
	{
		return null;
	}
	public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn) 
	{
		return null;
		
	}
}

Here is my main class:

// Commented out imports

// The value here should match an entry in the META-INF/mods.toml file
@Mod("minormagicks")
public class MinorMagicks
{
	public static MinorMagicks instance;
    private static final Logger LOGGER = LogManager.getLogger();
    public static final String MOD_ID = "minormagicks";
    public MinorMagicks() 
    {
    	instance = this;
    	
    	final IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus();
    	
        modEventBus.addListener(this::setup);
        modEventBus.addListener(this::doClientStuff);
       
        ItemRegistryHandler.ITEMS.register(modEventBus);
        PotionRegistryHandler.POTIONS.register(modEventBus);
        MinecraftForge.EVENT_BUS.register(this);
        MinecraftForge.EVENT_BUS.register(new MinorMagicksForgeEventHandler());

    }

    private void setup(final FMLCommonSetupEvent event)
    {
    	MagicksItemColors.registerColors();
    	PotionRegistryHandler.replaceRecipes();
    	MagicksPotionBrewing.init();
    }
    private void doClientStuff(final FMLClientSetupEvent event) 
    {
    	
    }
}

My model json for my item:

{
  "parent": "item/generated",
  "textures": {
	"layer0": "minormagicks:items/gelled_potion_liquid",
	"layer1": "minormagicks:items/gelled_potion"
  }
}
