Does coloring always protect frogs from enemies?

Amphibians, like many other animals, have a protective or adaptive coloration. This color allows them to remain unnoticed by predators. The color of the animal depends on which substrate prevails in its habitat. Also, some frogs have adapted to adapt to the environment by changing their own color (like chameleons).
But the protective coloration does not always help to avoid predators, since any movement leads to the fact that the disguise will be exposed. In addition, the animal may find itself in a place where the adaptive coloration, on the contrary, will highlight it.
