Mango Martinis

Of course, there's no such thing as a mango (or apple, or chocolate) martini. They're just a bunch of fruity drinks in martini glasses... "So how do you like the vodka one compared to the gin? it's a lot smoother, right? Like, it's not as sour?" asked the waitress, Kerry. "well, they seem to like the vodka one better, but I think they're both pretty good. I mean, the gin one tastes like the green mangoes, while the vodka one tastes a lot like ripe mangoes." "So, whaddaya think if maybe we served the gin mango martinis with a little green-colored liquor, while the vodka martinis we served in the usual yellow-gold?"
