Pacific Lime Mold

So, what makes this "Pacific" exactly?  The green colour?

Welcome to the second entry in my Season of Jellied Things series.  The Pacific Lime Mold is another recipe from Betty Crocker's New Good and Easy Cook Book (published 1962).  There was no picture  of the finished product in the cookbook, so I was a little perplexed about what made this lime mold "Pacific", per se.  Does the lime Jell-O take on the colour of the ocean when combined with the mayonnaise and other ingredients?  Or is it more of a [pineapple = tropical = Pacific] sort of equation? Oooo... venturing into unknown territory!  Here there be dragons!
