The Rainbow Mountains of China within the Zhangye Danxia Landform Geological Park are a geological wonder of the world. These famous Chinese mountains are known for their otherworldly colors that mimic a rainbow painted over the tops of rolling mountains.
All of those photos have filters etc. Beautiful rock formation, but they do not look like that. Maybe they would be half that vibrant if they are wet while the sun is out like a sun shower or something.
Actual link I provided in the body shows one perspective of shots. Overall is single image of them could be modified or blurred the same reason I posted the results from the cloud. What's something looks that unreal I usually look for multiple sources.
Perhaps I'm overthinking it. Living forward I'll just post single source images.
