Light quality shows strong effects on humans in many aspects, including aesthetics, psychology, physiology, and health. By assuming that natural light has the best light quality, devising a pseudo‐natural light is hence important and critical. Here, an all‐weather pseudo‐natural light is demonstrated based on a high number of broad‐band emitters. By doping six broad‐band organic light‐emitting dyes in three separate emission layers, for example, the light source can exhibit a 92–96% similarity with the sunlight from dawn to dusk, and a color gamut of 80% in terms of NTSC. By combining six narrow‐band light‐emitting diodes (LEDs), a much wider gamut of 121% NTSC is achievable, but with a slightly poor daylight similarity, i.e., ranging between 80% and 83%. The daylight similarity, however, can easily be enhanced to at least 94% upon incorporating broad‐band phosphors, even with the use of only one or two LEDs.
