Filter > Sketch > Charcoal (Chalk & Charcoal)

I am trying to make an old black & white photograph look "charcoal like" for my boss

When I use the Charcoal or Chalk & Charcoal filters it turns the fully black & white photo orange or orange & green and my boss insists that there is a wrong setting with the filter

Is there a wrong setting or is this just the nature of the filter?

Is there another way to apply this effect?
