Disclosed herein are implementations of a radiative cooling formulation, an apparatus including a substrate coated with the radiative cooling formulation, and a method of applying a coating of the radiative cooling formulation to an object. In one implementation, a radiative cooling formulation includes a binder which includes a first polymer and a second polymer that are practically water insoluble and are substantially non-absorbing to light having wavelengths in a solar spectrum. The radiative cooling formulation further includes a solar reflector material embedded in the binder.
