A transparent radiative cooling film includes an ultraviolet/infrared (UV/IR) cut layer and a radiative cooling layer extending across the UV/IR cut layer. The UV/IR cut layer may be formed by alternating layers of oxide and metal and/or by a color filter layer. The radiative cooling layer includes an oxide. The UV/IR cut layer is transparent to a first range of electromagnetic radiation in the visible spectrum, reflects or absorbs a second range of electromagnetic radiation in the UV spectrum, and reflects a third range of electromagnetic radiation in the IR spectrum. The radiative cooling layer is transparent to the first range of electromagnetic radiation in the visible spectrum and emits a fourth range of electromagnetic radiation in the IR spectrum with wavelengths between about 7.0 micrometers and about 18 micrometers such that the transparent radiative cooling film preserves the color of a surface while passively cooling the surface.
