Any tips increasing the colors on my pac man frog?

My fantasy looks very similar to that pic above. Usually changes bright lime/orange and some different brown. Usually after it soaks also

My cranwelli goes from really dull to having some really nice greens and yellows in just the few minutes it takes to soak too. I've even noticed a big color difference when she's been buried completely versus when she's sitting mostly on top of the coco-fiber.

Some don't darken at all on Coco Fiber. Sam Blues never darken on it and neither do Blue Line Ornates The darkening is natural. They darken to disguise themselves so as to not be eaten by predators and for security in their environment.
