By using different colors for the minimum and maximum reflection. This
however will only make the color of the reflection change, not the
pigment, but combined with heavy reflection blurring, this might look
good.

Here's some sample code, but it doesn't have blurred reflection:

sphere {
   0, 1
   pigment {rgb 0.1}
   normal {bumps 0.5 scale 0.15 turbulence 0.5}
   finish {reflection {<0.1,0.2,0.5>, <0.4,0.8,0.4>}}
}
light_source {<1,2,-3>*1000, color 1}
camera {location -4*z look_at 0}
background {rgb 1}

Another problem is that you can only blend between two colors with
variable reflection, but that might also not be a big problem.
