Quote -  the skin is pale coz of the subject of the picture

That is perfectly fine, you can have surreal skins with Reality and Lux, just make sure that you use colors that could be realistic, as in "physically plausible". For example, if you have an actor in a movie who needs to have pale makeup there will be no possibility for thast makeup to reflect 100% of the light. That is what pure white, 255,255,255, does. It simply doesn't exist in nature. So, a very light shade of grey, 199,199,199, together with lighting, will do the trick while still being physically plausible.

Hope this helps.
