Ok as silly as this may sound let me expand on why I want to know....I LOVE SI's cartos don't get me wrong but I think it would be cool once in awhile to put a tiny bit of coloring in my juice to match my battery and drip tip....for going out. Not an all the time thing at all. Red with red batt, blue with blue batt, etc. Just for holidays, etc.
You're such a girl

....Could our great "Imagine" shed any light on this matter?
