There seems to be an unwanted feature in pov 3.0, 3.1 and 3.5 where
checker and ramp_wave or poly_wave (as used below) do not behave as
expected. I would expect the default pigment to be ignored here and
not affect the box. Docs 6.7.12.3 don't seem to mention anything that
would give a clue.

// OK without this line:

box{ -2, 2
   pigment{
      wood
      color_map{[0 rgb 0][1 rgb 1]}
      ramp_wave // Disable this to clear problem.
   }
}
