So many sports drinks have bright rainbow colors. I don't think my kids need any more artificial coloring than they already get with their skittles and other colorful candy. However they want something beyond plain water so we've been using Crystal Light Pure. For awhile I found it packaged as Pure Fitness. So far Walmart has had the best price at as low as $2.00 a box. However lately it has been hovering around $2.50. One of our favorites is mixed berry.
I also have been finding Gatorade that is clear without added artificial sweetners and colors. My son says it tastes better than the artificially colored and flavored ones.
