When two samples with different albedo, white and green sand, are exposed to equal amounts of radiation, will?
Potentially (usually) yes. Unless you rigged the experiment with a particular shade of green and a particular wavelength (or spectrum) of radiation. The green sand will reflect less heat, therefore will become warmer. Though initially at the surface, this heat difference will eventually be conducted into the sand. And air near the surface will be heated by the sand resulting in increased temperatures above the sand too.
