Color maps fade from 0 to 1 linearly, but the spherical pattern
is going along a curve. You can tweak the location and color
to suit what you want in the color map. The colors are added
to the background color, white tends to saturate...

However, the spherical pattern is located at the origin, to move
it you need to define it at the origin, and then translate it.
You won't see the spherical pattern if you just place the container
object elsewhere.

This is correct:
sphere {<0,0,0>,1 hollow material{glow} translate <0,1,0>}

This is wrong:
sphere {<0,1,0>,1 hollow material{glow} }
