POV-Ray 3.7 does not have any native mechanism to obtain depth
information, so you'll need to design your scene in such a way that the
colours in the image happen to depend on the distance to the camera.

The most straightforward way to achieve this is to disable the
individual textures of all the scene's objects, bundle those objects
into one big union, and assign a texture with a gradient or spherical
pattern to it, with an emission-only finish.

An alternative is to set all objects' textures to a plain white
emission-only texture, and flood the scene with an absorbing atmosphere.
Or set all objects' textures to a pitch black texture, and flood the
scene with an emissive atmosphere.
