For

This formula works for bozo, which is a direct use of noise.  However,
granite uses multiple iterations of noise, so this doesn't work.  However,
you can get very close results by simply dividing all indices by 2 and NOT
adding the 0.25.

For granite, the converted example should look like this:
color_map{
    [.1 rgb 1]
    [.25  rgb <1,1,0>]
    [.35  rgb <0,0,1>]
}

I tested this and it works great for T_Grnt9.

Also, make sure to convert rgbf to rgbt if layered textures with filter are
being used (not necessary for T_Grnt9).
