In general, none of them are absolute color-spaces and the last three (HSV, YCrCb and Lab) are ways of encoding RGB information. For color histogram, we need to convert the image from BGR to HSV. Since P(C pS) is only slightly bigger than chance, saturation provides almost no information, and can be discarded. Objects can have colors not defined in the palette and still be properly displayed.
