I like sahara which is an 08 S/S colour and should still be available in store. You can get it in RH (regular hardware), SGH (Silver giant) or GGH (Gold giant). The SGH gives it a cooler look and the GGH a warmer look. Just note that with the lighter colours they can be prone to dirt and stains easily and also colour transfer from your dark clothes.
-05 caramel is gorgeous (and -04 Marron and -05 Bordeaux although they may not be what you consider nuetral) but so is Sahara which you would probably be able to get in stores, Good luck in finding the right colour!
