  Render and study this. Perhaps it will help a little:

camera { location -z*3 look_at 0 angle 35 }
light_source { -z*100,1 }
box
{ 0,1
  pigment
  { gradient x color_map
    { [0 rgb <1,0,0>]    // The color map starts from red
      [.5 rgb <1,1,0>]   // goes to yellow
      [1 rgb <0,1,0>]    // and ends to green
    }
  }
  translate -.5
}

  Color maps are used to define the colors along a pattern type. In the
example above the pattern type is 'gradient'. The pattern goes from 0 to
1 and the color map specifies what colors are used which each value (all the
in-between values are interpolated).
  The color map doesn't specify the shape of the pattern, only the colors
used.
