   In a printed catalog the page curves towards the binding, so it darkens

   Two points are critical for the paper feel:
   • The shadow is not a narrow strip; it spreads over the WHOLE page — a
     very slight darkness remains even in the middle. A narrow band looks
     like a belt and feels artificial.
   • The colour is grey, not pure black; black makes the paper look dirty.
