What makes pink lemonade pink?
Dye, or you can use raspberries to achieve the pink color and flavor.
Pink food coloring?
Usually it's a little but f red grape juice. But many other food colors are used. My favorite is cochineal (http://en.wikipedia.org/wiki/Cochineal), a red food color made from tiny insects... yum yum!
Rats crawl into the lemon squeezers.. Jk that's gross!
dye in the mix
It's regular lemonade, but with food coloring.
