Why is your color_map so complexe? Why do you think that you need those 
black stripes? Why do you repeat the sequence 
black-blue-black-green-black-red 8 times?
Why don't you keep it simple?

How about this?

color_map{
  [0.00   rgb<0,0,1>]
  [0.97/2 rgb<0,1,0>]
  [0.97   rgb<1,0,0>]
  [1.00   rgb 1]
}

Or

color_map{
  [0.0      rgb<0,0,1>]
  [0.97/4   rgb<0,1,1>]
  [0.97/2   rgb<0,1,0>]
  [0.97*3/4 rgb<1,1,0>]
  [0.97     rgb<1,0,0>]
  [1.0      rgb 1]
}

You may also try substituting srgb in place of rgb to use the sRGB 
colour space instead of the linear colour space used with plain RGB values.
