NightAHawkinLight on youtube has been working on something similar. same kind of snow-like nanostructure to reflect light away, but with the added benefit of a paint that emits light in a wavelength that travels through the atmosphere without interacting with any of it.

so if you point a painted tile at the sky it will actually cool below ambient temperature, it’s pretty wild www.youtube.com/watch?v=N3bJnKmeNJY
