Yes, they're pretty same (one is a bit darker). What do you really expect from the acft? If you're in a VA of some sort, then it might be wise to think long-term (to suit the fleet et cetera); if you like long hauls - pick the 767, if not - take the 757. I think the latter gives more flexibility in choosing routes to fly. Dunno, take 767  :) (long hauls are great).
