Custom Colormaps for my Grass and Leaves

[alttbm]

I can't seem to Figure out how

 

 

Edit0:

 

Edit1: I Cloned The Default Grass and Leaves Blocks and changes them to show my textures, but that's pretty basic. I want to change the grass color and leaves color to my colormaps

 

Edit2: my grass block code      works but how do I use a custom grasscolor.png

    public void registerIcons(IconRegister register)
    {
        this.blockIcon = register.registerIcon(Reference.MOD_ID + ":" + (this.getUnlocalizedName().substring(5)) + "_side");
        this.iconGrassTop = register.registerIcon(Reference.MOD_ID + ":" + (this.getUnlocalizedName().substring(5)) + "_top");
        this.iconSnowSide = register.registerIcon(Reference.MOD_ID + ":" + (this.getUnlocalizedName().substring(5)) + "_side_snowed");
        this.iconGrassSideOverlay = register.registerIcon(Reference.MOD_ID + ":" + (this.getUnlocalizedName().substring(5)) + "_side_overlay");
        
    }
