What could happen to camouflage if the environment in which the animal lived changed in some way?

If the environment changes, the effectiveness of an animal's camouflage may diminish. For example, if a species that blends in with green foliage moves to a barren, rocky area, it may become more visible to predators or prey. Over time, this could lead to natural selection favoring individuals with better-suited coloration for the new environment, potentially driving evolutionary changes in the population. Conversely, if the environment stabilizes again, the original camouflage traits may become advantageous once more.
