Hi Dav,

Here's something that does what I think may be what you're asking for:
I've done a difference so you can see the white center.

light_source { <10, 20,-30> color rgb<1, 1, 1>}
camera {location <1, 1, -3> look_at <0,0, 0>}

difference {
  sphere {0,1}
  box {0,<1,1,-1>}
  pigment {onion
    color_map {
      [0 color rgb <1,1,1>]
      [1 color rgb <1,0,0>]
    }
  scale 1.001}
}

Regards,
Chris B.
