I'm probably way off, so perhaps you shouldn't listen to me, but are you just
describing the angle of incidence pattern?  I can't find it in POV-Ray, but I
know the aoi pattern is in MegaPOV.  If you had a physical model, you could
tabulate properties by angle to get the blue/yellow transition.  Of course this
approach isn't necessarily physically-based, but it sounds similar to what
you're after.
