The matrix operation is your problem. Without it, the demarcation in pigment
disappears.
It looks like pigments, matrices, and blobs don't work well together. Don't
know if this is a bug or what...
Simplified version of your code below, zooming in on the chin at an angle:
#include "colors.inc"
background{Blue}
camera{location<0,1,-10> look_at<-.6,0.4,0> angle 4 }
light_source{<5,5,-20> color White*1.5}
#declare head=
blob{ threshold .35
cylinder{<0,-.5,0><0,1,0>,.55,10
scale<1,.6,1>
//COMMENT OUT THIS LINE TO SEE SMOOTH PIGMENT//
matrix< 1, 0, 0, 0, 1, 0, 0,.4, 1, 0, 0, 0>
//YES, THAT LINE ABOVE THIS ONE!
}
sphere{<0,0,0>.3, 2 scale<1.2,.6,.5> rotate x*-45
translate<0,-.6,-.35>}
texture{pigment{Yellow}}
}
object{head rotate <90,90,0>}
