hey guys. i get most of my e juice form mtbakervapor. a lot of the flavors that i like (all 6 mg nic) are very light in color and most of them are nearly clear. i was wondering if it was a bad idea to put food coloring into them just to give it a little style. i have an aspire nautilus which is a big bold tank and the juice is very visible so i think adding a little flash of color would make my setup that much cooler looking. i was thinking like a drop of green coloring in my green apple, red in my watermelon, blue in my cotton candy, etc., does anyone know if this is bad? can this cause some sort of bad chemical reaction in the e juice? is it harmful to inhale food coloring?(i can't imagine it would be any worse than all the chemicals already mixed in e liquid) has anyone done this before? thanks for any help guys
