I agree that this would be one possibility, but how would this relate to
the book?  Distinguishing between a rainbow of light and a "rainbow"
of gravity would imply that it is a something about the spectral 
characteristic of gravity which is important, not the spectral 
spreading which "rainbow" alone would be sufficient to evoke.

Here at work we've concluded that a metephorical gravitational rainbow
could exist.  However, in order for it to be considered reasonably
analogous to a normal rainbow, it would have to be only those portions 
of the gravitational spectrum which we are sensitive to, since the 
rainbow is considered to only be composed of those parts of the EM spectrum
which we can see.  Trying to conjecture what this would feel like gave us
a collective brain cramp.  Trying to envision what would cause one to
arise wasn't much better.  Seems to me that the shape and the elusive
endpoints of the rainbow are more obviously connected to the novel than
are the spectral characteristics.
