The invention relates to a neutral color optical film, and belongs to the technical field of films. The neutral color optical thin film is arranged on the surface of glass and comprises N dielectric layers, a metal functional layer and a discontinuous metal layer, wherein one dielectric layer is adjacent to the glass; the metal functional layer or the discontinuous metal layer is arranged between the two adjacent dielectric layers; the discontinuous metal layer comprises a discontinuous island-shaped precious metal layer and a metal barrier layer, and precious metal is selected from one or more of gold, silver, platinum and palladium; wherein N is greater than 2. After the neutral color optical thin film is subjected to standard high-temperature tempering, hot bending, interlayer and other processing procedures, the neutral color optical thin film not only has excellent photo-thermal selection performance, but also can ensure that a * and b * of the transmission color are within the range of-1.5 to 1.5. 本发明涉及
