Since you've decided on the mini, my vote is for beige! It'll go with everything you bring on your trip.
If you are still open to suggestions for a travel bag, Balenciaga has great large sized bags that are really light and beautiful. (I prefer lightweight bags) I'd use a Balenciaga bag during the traveling (airport) and shopping jaunts but use the mini for the evening/more formal events.
Looking at your beige Chanel, I kinda want one too now! Uh oh...
