I would do mostly orange with maybe a half packet of red the pink lemonade isn't strong enough a color to overcome the orangishness.
It would be ideal if you could find a koolaid color that is hot pink and then add just a wee wee bit of yellow or orange.
If all else fails go n get yourself some wilton food color gels and use them instead. They are the same thing as the koolaid colors anyway without the flavor. And they do have a peachy red almost coral looking color.
