   Color: warm uncoated paper, deep navy-black ink for every piece of running
   text, and two fluorescent inks — pink and teal — that multiply where they
   overlap to make a third color, the way two passes through a risograph do.
   The fluorescent inks are only ever used for graphics and large display
   type. Running text stays in the navy-black ink, or in the off-white ink on
   dark paper, so contrast always clears WCAG AA.
