Food Dye in water?

was wondering if anyone has ever tried just putting food coloring into the water being fed to the plant during the last few days of flowering... thinking it would change some sort of color?

does it still smoke fine?

I know of some wogs that used to spray their heads after harvest with coca cola. Another thing ive done is pull tree out of medium and dip roots in stong sugar water then hang up to dry and cure. mates have used vodka to

fdd said they tasted like crap after they were colored
