Multicolor organic room temperature phosphorescence (RTP) has garnered wide research attention due to the long luminescence lifetime and tunable excited state properties, which show great potential in displays, anticounterfeiting, data encryption, and sensing. However, because of the sensitivity of triplet excitons of organic materials, the triplet emitting level of organic compounds is hard to manipulate. Therefore, realizing multicolor RTP in organic materials is still a huge challenge. In this review, we summarize recent advances in multicolor organic RTP materials, including the underlying luminescence mechanisms, design principles of multicolor phosphorescence, detailed photophysical behaviors, and their potential applications. The last part presents existing challenges and future perspectives, such as expanding the color gamut, enriching stimuli-responsive properties, improving the phosphorescence performance, and exploring more advanced applications. This review will provide inspiration and guidelines for constructing multicolor RTP materials and expanding their potential applications in organic electronics, bioelectronics, flexible electronics, and so on.
