It's easier to diagnose and solve a problem it there is code posted
The code below works (pov 3.5)

#include "functions.inc"

camera { location <0,4,-10> look_at <0,0,0>}

light_source {<-5,5,-20>  rgb 1}

light_source {<5,5,10> rgb 1}

isosurface {
 function {y-f_noise3d(x*3,0,z*3)}
 max_gradient 5
 contained_by {box {<-5,-1,-5>,<5,5,5>}}
 pigment {
  bozo
  scale 0.5
  color_map {
   [0.0 rgb <1,0,0>]
   [1.0 rgb <0,0,1>]
  }
 }
}
