I got nuthin' -- I like all their colours, including yes to the Olive, even though their "amethyst" is a little too bright for my tastes, I even like the Kelly green..I mean, "forest".
And yeah, the Saffron does look pretty damn good in person. And the black looks pretty classic, too, as do some of the more subdued colors like charcoal and khaki.
Basically, it's a no lose situation. Just pick one, damnit, and you'll probably like it. I'm not a blue person, but IIRC, you are, so I'd go Mariner if you are.
