Adgen silver with a FOC is a tough pick since as you stated silver is usually chosen as a FOC color. I myself haven't seen Silver with any foc colors, but I'll keep my eyes peeled. If I were you I would get yellow since yellow being a bright mellow color would give a more believable FOC effect for Aegean silver in my opinion.
Here are some Foc video of other colors
