The development of radiative cooling coatings is of great significance inaddressing global warming and reducing energy consumption. In this paper，the functional materials used in three types of coatings includig white，colored and transparent radiative cooling coatings were introduced. For white radiative cooling coatings，single-layer and double-layer radiative cooling coatings were discussed separately according to the differentcoating structures. For colored radiative cooling coatings，three coloring strategies such as photoluminescence，thermochromism and structural color were introduced. For transparent radiative cooling coatings，the implementation of visible light transparency in radiative coolingcoatings by transparent substrates loaded with functional materials，such as SiO₂，Al₂O₃，PDMS composites and cellulose nanocrystals was reviewed. Finally，the perspectives on the development of radiation cooling coatings in practical applications were proposed.
