The present invention provides an underwater image color restoration method. In the method, 8-bit RGB pixel values of pixels in an underwater image are converted to a linear sRGB space for adjustment processing, adjusted pixel values are converted to 8-bit RGB pixel values, and then the acquired 8-bit RGB pixel values are fused with the adjusted pixel values to obtain a restored underwater image. Therefore, a foreground object in the underwater image or an underwater video processed using the solution of the present invention is natural and rich in color; in addition, the natural blue and green colors of background seawater are preserved, and the viewing effect of an entire picture is improved significantly and is comparable to or even better than the effect that can be achieved in the past after considerable manual toning.
