Colorspaces are ways of describing colors to fit the requirements of a particular application (e.g. Television, offset printing, color monitors). Color reduction, by default, takes place in the <i>RGBColorspace</i>. Empirical evidence suggests that distances in color spaces such as <i>YUVColorspace</i> or <i>YIQColorspace</i> correspond to perceptual color differences more closely han do distances in RGB space.
