Without labels I have a difficult time telling the difference between Olive Green, Olive and Kiwi. Lets throw Jungle into that group as well. At least Kiwi and Jungle will usually have the date etched on the bottom which will determine what you have. I think that Olive Green is more green and Olive has or can have a slight yellow/amber cast to areas of it. What I am trying to tell you is that I think this is Olive but don’t make any wagers on that.
Blog Update-November 28, 2013: It is nice to clear up this confusion. On my recent visit to Blenko I was told that Olive is the exact same formulation as Olive Green. AND Kiwi is the same as Jungle, only the names are different. Also this water bottle has the raised ridge bottom on it so we can be fairly sure that it is not technically Olive Green even though there is no difference in the color.
