1. A method, comprising: performing, by one or more computing devices: converting a stereoscopic image pair from a first color space to a second color space, comprising mapping color values in the first color space to color values in the second color space, wherein the second color space is more perceptually uniform than the first color space; generating a color-matched stereoscopic image pair in the second color space, comprising applying a respective transformation for each of a plurality of luminance ranges in each image of the stereoscopic image pair, wherein the transformations are applied to the color values in the second color space dependent upon a contribution of each of the color values to each of the luminance ranges; and mapping the transformed color values in the second color space back to the first color space to provide the color-matched stereoscopic image pair in the first color space.
