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.
