One of the things I did quite well with while around LAX was getting jets with special color schemes. Plenty of airlines are painting aircraft in something other than the normal house colors. This can be a livery that is part of their alliance, like OneWorld or Skyteam, or it can be something special of their own. It might also be a tie up with another organization.
Whatever the reason, it certainly makes things more interesting to get something that is a little different to break up the monotony of the regular fleets. Here are a selection of some of the different colors that were on display while I was out west. The Alaska scheme is not too apparent since the shot is head on but you can see it if you look. Others are more obvious. Hope they are worth a look.
