In both RGB and CMYK colors go neutral as they approach white and black, so color mode would have little effect, particularly since it uses the hue and saturation of the applied color but preserves the luminosity of the underlying layer. A white anything will respond with little more than a pale orange in shadow areas and not much at all in highlights. Murray has it; gradient maps are the way to go. That way you preserve the relationship between lights and darks, but you shift the entire profile into the new color range, including luminosity values.
