can someone help me with changing colours of items and blocks? I'VE BEEN TRYING FOR THE PAST WEEK (1.18.2)

package net.ajayxd.resource_trees.client;



import net.ajayxd.resource_trees.block.ModBlocks;
import net.minecraft.client.color.block.BlockColor;
import net.minecraftforge.client.event.ColorHandlerEvent;

import java.awt.*;

public class colourHandlers  {

    
    public static void PETRIFIED_COLOUR(BlockColor blockColor) {
        
    }
    public static void RegisterBlockColours(ColorHandlerEvent.Block event)
    {

        event.getBlockColors().register(null, , ModBlocks.PETRIFIED_LEAVES);

    }

    public static void RegisterItemColours(ColorHandlerEvent.Item event)
    {



    }
}

I've looked around for any tutorials that show how to do this. The only things I've found is:

ColorHandlerEvent,

BlockColors

and ItemColors.

HOW DO I USE THEASE???? or is there a better way I don't know about?

ANY help would be appreciated.

Edit I give up I'll figure it out one day don't bother saying anything
