Color Enhancing

[Rhyno47]

I bought this product the other day and have started to feed it to my Painted Turtle as well as my Box Turtle. It promises to induce color due to the krill and a few other high color ingredients. Has anyone ever used this before? Does it work?

I always fed color enhancing Koi food to my Eastern Painted's and I don't know if it worked or not, but their colors were always nice and red.
