does the D7200 have a choice of modes to alter the color? lower level (amateur) Nikons do but they considered the 7200 a pro body so it might not have that

another easy way to do this is to change the light source or use a filter on the lens

otherwise you need to do it in post with Pshop or Lightroom or whatever

and... the monitor used will affect how the colors come out so yours may differ from the customers
