       Color reduction, by default, takes place in the RGBColorspace. Empirical evidence suggests that distances in color spaces such as YUVColorspace or
       YIQColorspace correspond to perceptual color differences more closely than do distances in RGB space. These color spaces may give better results when
       color reducing an image.
