I've been trying nearly everything and can't really find this out. I just ordered some parts and I've tried everything to get the color matched up to the broken, original parts I have on my vintage les paul

Just to make sure, I plan on using these same parts and my budget is REALLY low, any tricks to age the pics?

I've tried soaking it in coffee overnight, throwing it into a crude mixture of instant coffee and coffee bean mix, tried grinding in coffee beans, ground cinnamon, and even desperately dipping my parts in maple syrup. Although the coffee looked good, the second a drop of sweat got on it, it ruined the entire effect.
