Martin, As near as I can tell from their website, Stouffer's stepscales and other products are only calibrated for density, not for color balance. I already own a couple of their stepscales and the opaque one is distinctly brown, not neutral gray. When I querried them on it the response I got was that they meet the "industry standard" for neutrality. Thanks for your reply, Frank
