If you wanted, you could actually incorporate all those colors -- make a layered drink! You just need to find things with the right density -- heavier alcohols on the bottom (liqueurs), lighter ones on the top. It makes it easier if you do "slushy" type drinks, because you can modify the densities by planning with the water/sugar contents. Here's something you could do with a slushy drink: http://www.coastalliving.com/food/kitchen-assistant/seven-variations-classic-margarita-00400000046611/page6.html You could do frozen watermellon for the pink, and maybe bits of frozen kiqi for the green? And then for the navy, maybe some blue curacao (it's orangy like triple-sec), or some hpnotiq like in this recipe? I've also seen recipes with pina-colada mix and grenadine / strawberry for pink. Though with that, the pina colada mix would have to go on the bottom though (since the pina colada would be the most sugary) I haven't tried these personally, but there's definitely some experimentation you could do if you wanted Just figure out the densities and be reallyreallyreally careful when you pour. Or not -- you can put the drink in the fridge, and it'll all eventually separate out to it's proper densities in a few hours
